Installing the whole GCC family

[Akim Demaille]

Hi all,

As a package developer, I need to run as many compilers as I
can on my machine.  I'm very happily running gcc42 up to gcc48
for instance.

However, when I try to install gcc49, I get a conflict :

 $ sudo port install gcc49
 --->  Computing dependencies for gcc49
 Error: Unable to execute port: Can't install libgcc-devel because conflicting ports are installed: libgcc

What can I do to have the whole GCC family installed?

Thanks in advance!
