[vtk-developers] certain libraries included twice

[David Gobbi]

Thanks Bill, Andy,

I'll hack my makefiles for now.  Rebuilding my glibc isn't really an
option (or at least not one I'm willing to consider ;).  If I get any
additional insights into why the g++ linker is barfing on the double -lm
I'll report back.

Rebuild your glibc, and this time don't include the --disable-versioning or --enable-oldest-abi flags.
