Help with porting FreeCAD

[Andrea Venturoli]

Hello.

A while ago I dirty-ported FreeCAD 0.14 and more or less got it working.
Now it won't work anymore due to incompatible changes in OpenCASCADE 
(which is a dependency); so I'm trying 0.15 (which is still a beta).

The box I'm using runs 9.3 and I'm facing a problem I'm too 
inexperienced about the port system to solve:

_ g++ 4.9 seems to be needed (previous versions having an unsolved bug), 
so I put "USE_GCC=4.9";
_ however, fortran is required and "USES=fortran:gcc" picks up gfortran48;
_ so in the link stage "-L/usr/local/lib/gcc48" comes before 
"-L/usr/local/lib/gcc49" and I get unresolved symbols.

Is there a way I can tell the port system to pick gfortran49 instead of 
gfortran48 and forget about "-L/usr/local/lib/gcc48"?
Of course I could try uninstalling gcc-4.8.4, but this is unfortunately 
a run dependency of several other ports.


  bye & Thanks
