[GRASSLIST:1201] Re: r.mapcalc error

[Bill Dickinson Jr]

Just for everyone's edification, here is where I am at on this error.

I tracked down one reference to readline errors under OS X -

	http://www.astro.washington.edu/owen/InstallingPython2.2.1OnJaguar.html

This document gives instructions for installing readline on 10.2 with 
a change in the /support/shobj-conf file. This change is recommended 
because "With 10.2, ncurses stuff was moved from the System library 
to external libraries and the process for dynamic libraries changed."

I downloaded readline 4.3-5, removed readline through my Fink 
installation, and went through the process of installing readline as 
outlined in this document. The install went fine, but the change did 
not fix the error I receive when trying to use r.mapcalc in GRASS 
5.0.2. I still get:

GRASS 5.0.2 > r.mapcalc
dyld: r.mapcalc version mismatch for library: 
/usr/local/lib/libreadline.4.dylib (compatibility version of user: 
4.2.0 greater than library's version: 4.0.0)
Trace/BPT trap

Reading this, does it mean that GRASS 5.0.2 has something in it that 
is looking for 4.0.0 while my OS X version of readline is actually 
4.2.0 (or is it the other way around)? If so, can someone look into 
fixing this somehow if the fix is worth the time?

For now, I will take Hamish's suggestion and recompile GRASS 5.0.2 
*without* readline. ;-)

Thanks.
Bill
