Right. I used the pic archive to ensure proper linkage with the rest of
the code.

I think so, yes.

The problem seems to be in the pkg-config script of the older libftgl.
I reports back the library -lftgl only - not -lftgl_pic. So what I did
I replaced -lftgl with -lftgl_pic around line 1496 in the configure
script:
ftgllibs=`pkg-config --libs-only-l ftgl | sed s'/-lftgl/-lftgl_pic/'`
I don't see an easy way to remain back-ward compatible with etch, so I
think the should be replaced with
ftgllibs=`pkg-config --libs-only-l ftgl`
Of course, this will cause some lintian warnings (non-PIC code) on etch,
but should be clean in sid and lenny.
Yours,
