"deflate" comes from zlib (libz), which provides "gzip"
(de)compression. All programs which are linked against libgis also
need to be linked against libz.

AFAIK, the correct way to do this is to ensure that any program whose
compilation command includes $(GISLIB) also includes $(XDRLIB). 
However, unlike $(GISLIB), $(XDRLIB) should not be listed as a
dependency, as it is a list of compiler/linker switches rather than
the pathname of a library file.

For an example, look at virtually any "Gmakefile".
