spack find doesn't search virtual deps properly

Subject: [spack] Would like 'spack find' to find implementations of a virtual dependency

I went looking for blas implementations. . .

[scratlantis:~/tmp] miller86% spack find blas
==> No such package: blas
[scratlantis:~/tmp] miller86% spack find netlib-blas
==> 2 installed packages.
-- macosx_10.8_x86_64 / gcc@4.2.1 -------------------------------
netlib-blas@Nov2013  netlib-blas@3.5.0

So, I am thinking spack find should find all blas implementations and not just a specific one.

Or, maybe if a find for the package as a specific package fails, then attempt same as a virtual dependency

spack providers gives you this info, but I agree with Mark that Spack find should work with simple virtual dependencies.

@tgamblin I think this has been fixed by the reworking of spack find to use anonymous specs:
