Spack dependency resolution and normalization broken #1552
Description
I'm on the latest develop branch and having problems specifying an installation. I want to build parallel NetCDF and NetCDF-Fortran with PGI. OpenSSL and libpciaccess can't be built with PGI, so I'm linking to GCC versions. When I run:
$ spack spec netcdf-fortran %pgi ^netcdf+mpi ^openssl%gcc
Input spec
------------------------------
netcdf-fortran%pgi
^netcdf+mpi
^openssl%gcc
Normalized
------------------------------
netcdf-fortran%pgi
^netcdf+mpi
^curl
^openssl%gcc
^zlib
^m4
Concretized

It works. But when I also specify the compiler to use for libpciaccess:
$ spack spec netcdf-fortran %pgi ^netcdf+mpi ^openssl%gcc ^libpciaccess%pgi
Input spec
------------------------------
netcdf-fortran%pgi
^libpciaccess%pgi
^netcdf+mpi
^openssl%gcc
Normalized
------------------------------
==> Error: netcdf-fortran does not depend on libpciaccess
