Re: dlsym() broken on alpha?

[Bibek Sahu <scorpio dodds net>]

	On a redhat 5.1 system, you probably don't have /lib/libm.so.
Change that to the name of the file that is actually on your machine.  It
might be handy if you use the other chunk of code in the man page, the
chunk that checks for errors every step of the way and tells you what went
wrong. ;-)

Good Luck!
If you need any more help, lemme know.
