The build system is trying to link libgis against libz, but libz is a
static library which contains non-relocatable code and thus cannot be
linked into a shared library.

The preferred fix is to force the use of a shared version of libz. I
have no idea where the linking command is getting the
/afs/isis/pkg/zlib-114/lib path from; it doesn't appear in the link
command.

Alternatively, try removing $(XDRLIB) from the definition of
EXTRA_LIBS at the top of lib/gis/Makefile (you may have to do the same
for other libraries).

Note that this will result in a static copy of zlib being linked into
every executable, which will increase the amount of disk space which
the GRASS installation requires.
