I recently upgraded from Mac OSX 10.5 to 10.6.2 (Snow Leopard). I've been successfully using a Plplot installation that I got through Fink (version 5.6.1). I use this with the Intel ifort Fortran compiler by including `plplot-config --cflags --libs --with-f77` on the load line. However, the 10.6.2 upgrade seems to have broken things for Plplot (see below). I can still run codes using Plplot that were built before the upgrade, but cannot build new versions. Any suggestions as to how to fix this?

My /usr/lib area has /usr/lib/libltdl.a and /usr/lib/libltdl.dylib, but no /usr/lib/libltdl.la.

-Thanks, Don
