This seems to be true for most BSD and UNIX systems.

If you use
SHLIB_LD="${CC} -shared"
you must also use
LD_SEARCH_FLAGS='-Wl,-rpath,${LIB_RUNTIME_DIR}'

You would also need to patch configure or run autoconf (version 2.13).

PS: grass 7 compiles for me on FreeBSD 9.0 with SHLIB_LD="ld
-Bshareable -x", even though it should actually fail.
