Undefined references

[Troy Jacobson <jacobso6 midplains net>]

I've been following the gnome development for some time now, and have
had varying degrees of success.  This latest problem has me a bit
stumped:

When compiling, I get these errors (in this case both gwp and aorta):

/usr/lib/libgdk_imlib.so: undefined reference to `DGifGetExtensionNext'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifGetRecordType'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifGetImageDesc'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifOpenFileName'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifGetLine'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifCloseFile'
/usr/lib/libgdk_imlib.so: undefined reference to `DGifGetExtension'
/usr/lib/libgdk_imlib.so: undefined reference to `PrintGifError'

I'm running RH5.0, and have been using the RPM snapshots.
