You mean that GRASS (which version) did not work or that g.extension within
it failed? Note that there is a known bug for g.extension usage in the Makefile
system due to a wrong path which also manifests in OpenSuse.

(that's fairly old...)

It would be needed to fix for many platforms this bug:
http://trac.osgeo.org/grass/ticket/620

In general, please use 6.4.0 (or 6.4.svn).

It needs to be compiled. You can manually fix the path in
include/Make/Platform.make (see above ticket), then g.extension
should work. Yesterday I made an attempt to also fix the
system wide installation (in GRASS 6.5) which might be
backported.
