Building file 4.26: duplicate symbol?

The MacPorts "file" port has no maintainer, and is still at 4.25, although
file 4.26 has been released (http://www.darwinsys.com/file/). I'd be happy
to try my hand at maintaining the port, but I can't actually seem to build
the thing. So this isn't a MacPorts question, per se, but I'm hoping
someone has run into this while building other not-designed-for-Mac
software. I've asked on the "file" list, but there's very little volume
there, and I don't know if any of the authors even has a Mac.
The problem:
When building file 4.26, on OS X 10.5.4 Leopard, I get a duplicate symbol
error from ld. I don't know enough about object modules to debug unaided,
but if someone can let me know how to troubleshoot this, I'm happy to dig
further.
4.25 builds fine on the same machine; 4.26 builds on my Fedora machine. I
also tried:
make distclean
autoreconf
./configure
make
but the same thing happened. There's an interesting bug at
http://issues.sxemacs.org/show_bug.cgi?id=42 which may be related;
apparently Apple's gcc does something different with inlines and C99? My
C-fu is rusty (and predates C99).
The error:
ld: duplicate symbol _li in .libs/apprentice.o and .libs/magic.o

make: *** [all] Error 2
The only debugging step I know:
macpro% nm src/.libs/apprentice.o | grep _li
0000cc40 S _li
macpro% nm src/.libs/magic.o | grep _li
000029f8 S _li
(NB: this symbol does not appear in either .o on my Fedora machine, although
"li" (no underscore) appears in both, as a [C]ommon symbol)
