provide more informative error message when package.py execs non-existent binary #30
Description
For instance, building bcftools is simply untar and make; there is no ./configure file in the tarball.
But the spackage developer (erhm, that is me) failed to remove the default
configure("--prefix=%s" % prefix)
As a result,
spack install bcftools
fails with
==> Building bcftools.
Traceback (most recent call last):

Certainly 'No such file or directory' tells me something is missing. Shouldn't it be more informative and tell me WHAT is missing?
