Apparently some versions of libc have exported this symbol, too; see  
http://lists.freebsd.org/pipermail/freebsd-bugs/2004-February/ 
005536.html, which concerned an equivalent problem but on FreeBSD. So  
it may not be Apple in particular, but (certain versions of) the GNU  
C libs.

I don't think it's a problem provided that the system libraries like  
libc and libm are listed late in the link command. The issue arose  
because the dvipng configure ends up putting -lm very early.

Checked in, after verifying that it builds on both OS X (PPC and  
Intel) and Linux (x86).
