Sorry to followup my own post, but further investigation has turned up another
potential problem.  This looks like it might be an issue at compile-time.
Basically, it didn't look like my statusmap was properly linked against libgd,
libgd, even though it appears to be linked (error free) at compile time.

% ldd statusmap.cgi
        libz.so.1 => /usr/lib/libz.so.1 (0xb75d2000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb75b0000)
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb758d000)
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb756f000)
        libc.so.6 => /lib/tls/libc.so.6 (0xb7437000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0xb75eb000)

ldconfig had created a symlink from /usr/local/lib/libgd.so.2 to
/usr/local/lib/libgd.so.2.0.0, but there was no libgd.so .. I created that
symlink, recompiled, and voila:

% ldd statusmap.cgi
        libgd.so.2 => /usr/local/lib/libgd.so.2 (0xb75a8000)
        libz.so.1 => /usr/lib/libz.so.1 (0xb759a000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb7578000)
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb7555000)
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb7537000)
        libc.so.6 => /lib/tls/libc.so.6 (0xb73ff000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0xb73ae000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0xb75eb000)

This is RedHat Edge Server 3.0.

Was this a real problem, or all in my head?  My status map was being updated
as I added new hosts, which suggests that it was at least able to use gd to
assemble the map image... but what was with the missing ld info?

I still haven't been able to get statusmap.cgi to show any custom icons, but
thought I'd drop this on the list and see if anyone had any insight.
