I was thinking that a virtual package would be good if we could use it to "trick" existing packages than use fft/blas/lapack into using the native versions. Is there any way of having a virtual package change the gcc flags of a package that depends on it?

John: It's not quite that simple. Most packages need to be patched to
use "-framework vecLib" instead of "-L%p/lib -latlas -llapack -lcblas".
The fft stuff is problematic since I'm pretty sure the vecLib fft has a
different calling interface than fftw. No virtual package is necessary -
any 10.2 package can safely link the vecLib framework since it is part of
the Dev Tools.

How easy would it be to write a virtual package that "provides: fft,
blas, lapack" for 10.2? I can do it if someone would tell me how to add
lines to the gcc string when another package builddepends on fft, blas,
or lapack.
