http://trac.osgeo.org/csmap/ points to
http://trac.osgeo.org/csmap/wiki/HowToGetTheSourceCode which seems to
indicate there is no release of the CS-Map code, so you'll be
building/installing from SVN.
However, like the previous poster, I agree that you may be better off
*not* using CS-Map, and using poj.4 at this time. CS-Map is a recently
open sourced project, and thus is still (in my estimation) in a
relative untested state of its current incarnation. proj.4, has been a
relatively stable project over the past long while, and is probably
slighly more tested in its current state. (And it has releases and
binaries for many packages due to this...)

I'd recommend this question isbest directed to the DO list rather than
included along with these other questions on this list.

I would typically use GEOS/OGR for that. I have no idea aabout its
compatibility with FDO, but I wouldn't be that hopeful.
