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!
