[tlbuild] Asymptote Build

[Richard Koch]

Philipp,

Your email was extremely useful.

My initial version of asy failed all of your tests, unfortunately.

Compiling on Leopard Intel,  I managed to find, compile, and install  
the fftw and gsl libraries. Then I threw away the .dylib versions of  
the lib files. After recompiling asy, I got a version which passed  
your first two tests, even after throwing away the fftw and gsl  
libraries. So I claim that I managed to statically link those  
libraries. (I still have to test by doing this on my actual build  
machines, which run Tiger rather than Leopard. But I suspect I can use  
those libraries.)

According to ./configure, the gc library was found and included.

Initially the OpenGL test failed, but that may be because Ghostscript  
wasn't installed. After rebuilding as above, all of your tests  
including the OpenGL test work. This means that if I compile on  
Leopard and then test on Leopard, all of the libraries work.

But actually we compile on Tiger and then run on Tiger AND Leopard AND  
Snow Leopard. So more tests follow. I'll let you know the results ...
