Steps to reproduce

I have two compilers installed - gcc 8.5.0 on the system, and [email protected] installed with spack. When I do a spack compiler list I see both compilers, but spack compiler find only lists the external compiler.

bash-4.4$ spack compiler list
==> Available compilers
-- gcc rhel8-x86_64 ---------------------------------------------
[e]  [email protected]  [+]  [email protected]
bash-4.4$ spack compiler info gcc
gcc@=8.5.0 languages:='c,c++,fortran' arch=linux-rhel8-x86_64:
  prefix: /usr
  compilers:
    c: /usr/bin/gcc
    cxx: /usr/bin/g++
    fortran: /usr/bin/gfortran

When I do a more specific query for gcc 13 (or 13.4.0), spack can't find it:

bash-4.4$ spack compiler info gcc@13
==> Error: No compilers match spec gcc@13

And a spack compiler find turns up no new compilers:

> spack compiler find
==> Found no new compilers
==> Compilers are defined in the following files:
    /decp/oar.gfdl.sw/cew_spack/an009/v1.0-2025.02-allowv4/spack/etc/spack/packages.yaml

Information on your system

• Spack: 1.0.2 (ee4990d)
• Builtin repo: spack/spack-packages@32c54f0
• Python: 3.11.11
• Platform: linux-rhel8-westmere

I am turning off local user configuration as part of this install, which has resulted in some non-standard path locations:

export SPACK_DISABLE_LOCAL_CONFIG=true
export SPACK_USER_CACHE_PATH=${SPACK_ROOT}/spack-dotfiles/.cache

General information

• I have run spack debug report and reported the version of Spack/Python/Platform
• I have searched the issues of this repo and believe this is not a duplicate
• I have run the failing commands in debug mode and reported the output
