Comment (by robe):

 nevermind read irc thread - irc thread here for posterity.  Though I think
 it's 4.7+ not 4.8+ and not even sure of that.  I just know our bot has
 been working fine on 4.7 aond postgis 2.1 so.

 library "/usr/lib/postgresql91/lib64/postgis-2.0.so" - Geographic
 Information Systems Stack Exchange (at gis.stackexchange.com)
 20:37:12        strk:   ah, >= 4.8
 20:37:21        strk:   but... how could his 9.1 install work ?
 20:37:43        strk:   watsonta: don't leave us out in the dark, let us
 know the detail ! :)
 20:38:42        watsonta:       Sorry - I just had to install proj and
 proj-devel. Broken yum dependencies in postgis package.
 20:38:51        watsonta:       Now it says that the clusters are
 compatible
 20:39:18        watsonta:       BTW, I'm on RHEL 6.5
 20:39:47        watsonta:       <strk> nailed it.
 20:40:14        strk:   so you weren't just upgrading postgresql but also
 changing proj4 version between the two install ?
 20:43:04        watsonta:       <strk> no - we were just upgrading from
 9.1 to 9.4
 20:43:12        watsonta:       <strk> no other changes
 20:43:25        strk:   via yum ?
 20:43:34        watsonta:       yes - via yum
 20:43:52        strk:   well, something must have triggered an upgrade of
 postgis as well, or a downgrade of proj4
 20:44:30        watsonta:       we have to upgrade from postgis 2.0 to 2.1
 as there isn't a 2.0 for 9.4
 20:44:34        strk:   as if the 9.1 version worked, either there was no
 need for the 'pj_get_spheroid_defn' symbol (older PostGIS version) or the
 symbol was included in proj4 library
 20:44:49        strk:   a-ha! that's the missing bit of information in
 your initial report ! :)
 20:45:20        watsonta:       and yet, this worked on multiple other
 environments (dev, qa, test, staging) without this problem
 20:46:17                * strk sees that the ./configure script in
 postgis-2.1 branch does not check for proj-4.8+
 20:46:20        strk:   worth a ticket
 20:46:21        watsonta:       seems like postgis-2.1 should have a proj-
 devel as a dependency. it wasn't even installed on this prod box, even
 though postgis-2.0 worked for 2+ years
 20:46:21        strk:   here's what it does:
 20:46:25        strk:   dnl Ensure that we are using PROJ >= 4.6.0
 (requires pj_set_searchpath)
 20:46:27        strk:   if test ! "$POSTGIS_PROJ_VERSION" -ge 46; then
 AC_MSG_ERROR([PostGIS requires PROJ >= 4.6.0])
 20:46:30        strk:   fi
 20:46:32        strk:   so builders are not warned about that
 20:46:48        strk:   althought good builders would "make check" before
 distributing a binary...
 20:47:00        strk:   watsonta: feel like filing a ticket for this issue
 ?
 20:47:19        strk:   AC_MSG_ERROR([PostGIS requires PROJ >= 4.6.0])
 20:47:25        strk:   ^^^ even in trunk (to be 2.2.0)
 20:47:32        strk:   but truth is we require 4.8.0+ since 2.1.0
 20:47:42        watsonta:       just glad it's working now. i will gladly
 file a ticket - where?
 20:47:46        strk:   http://trac.osgeo.org/postgis
 20:47:48        sigq:   Title: PostGIS (at trac.osgeo.org)
 20:48:10        watsonta:       I'm on it.
