Correct.

Okay, then you do need NCARG_LIB set, and you are setting it
to the correct thing.

This might be caused by how the "libncarg_c.a" library is built in
$NCARG/common/src/libncarg_c.

If you are on a little endian, 32-bit machine, you need to make sure
the following files are compiled into the library:

EXCSRCS = bcopyswap.c gsbytes.c logic32.c
SHLIBSRCS = g77.c

If you are on a 64-bit, little endian machine, then:

EXCSRCS = bcopyswap.c logic32.c
EXFSRCS = gbytes.f sbytes.f

I'm not sure this affects the fontcaps, however. It sounds like
somehow your i386/x86_64 builds may be getting mixed.
