Mm... my libtool responds with:
libtool: invalid tag name: CXX c++

Does this have to do with the "do not force use of your libtool"
request below ? Note that the `libtool' script is NOT shipped
with GEOS package, only the ltmain.sh script, as reccommended
in the libtool info page.

Maybe OpenBSD *needs* to explicitly link libstdc++ ?
I think we can safely always include libstdc++ link in postgis 
build scripts... they would not hurt.
Could you check that adding -lstdc++ in SHLIB_LINK line of lwgeom/Makefile
(around line 46) fixes the problem ?
