Notice that it's also not finding socket or nsl or anything. There is probably
some other error that's preventing the compiler from running to check this. I
had this problem at some point because I had mcpp installed and all calls to
gcc had some argument it didn't like. Look in mkmf.log for a more detailed
account of what it tried doing. What does it say in there?

Subject: [libxml-devel] installation problems on fc3
My installation attempt is failing, and claiming that I need libm.
I've included the output of a locate call also, which looks to me
like it includes a couple incarnations of libm.
So a couple questions.
How is it trying to find libm? Is there environment that I could be
setting to assist it?
How do I pass configuration options to gem (were I to decide to use --
without-libm), or do I have to do the tarball install to do that?
Any help would be greatly appreciated. Thanks.
