I'm not sure that I know enough about 5.7's build system not to make
The XDRLIB issue should be simple enough; anything which reads or
writes rasters uses parts of libgis which require the XDR functions
(opencell.c, get_row.c, put_row.c).
One issue is that it's hard to tell if it's correct with Linux, as GNU
libc includes everything which lives in $(SOCKLIB), $(INTLLIB) or
$(XDRLIB) on other platforms (except that $(XDRLIB) also incorporates
zlib, which should probably be a separate variable).
