This is usually the solution I also choose, especially when there are  
only few files to propose ... Do you experience the same problem with  
yours ?

Oh I understand now. At the time, I thought the problem was something  
else, i.e. relatively finding the libraries at runtime because of  
DYLD_LIBRARY_PATH.

Indeed.

I've tried to changed the "installed=" parameter to "true" (without  
the quotes of course) by editing basix/libtool and numerix/libtool  
but that does not make any difference. Maybe I did something wrong ?

We could try to propose a patch but that may take long time to  
develop and then, to be integrated. Another solution is choosing  
another, possibly cross-platform, build system ... maybe CMake which  
is more and more adopted by large scale projects.
