Do you have a Mac OS X machine to play around on?  If so, the way to 
get open source libraries (and software in general) is Fink 
(http://fink.sourceforge.net).  Qt versions 2 and 3 are available in 
Fink.

If you are planning to cross-compile, I know nothing about that.

The question isn't how to call the functions, but how to link the 
library.  I think (warning: I could be wrong) that gcc will generally 
tell the linker to use a dynamic library if it is available, and 
otherwise will link a static library.  I'm pretty sure that you can 
pass an option to gcc to change this behavior.

You might check out http://fink.sourceforge.net/doc/porting/index.php 
for some tips on porting apps to OS X.  It covers some weird little 
details that you should be aware of.

Good luck!
