mystery linking failure

[Nicholas Murphy]

I'm baffled by an "undefined symbol" linking error I'm getting.  I  
created a library using ar and ranlib.  Running nm clearly lists the  
relevant symbols in the text section, but when I try to compile, it  
complains that they are not there.  Compiling works just fine on my  
macbook, but when I try to compile in a Fedora linux box, I get  
undefined symbol complaints.  I've included the gcc output and the nm  
output below.

Any help is very much appreciated!

Thanks,
Nick
