Bad caches

When don't know how this happens, but it is possible to upload to our mirror a build with an incorrect path. Builds in caches are supposed to have padding so they can be installed anywhere. If they captured a non padded path, you might get a "CannotGrowString" error during installation

==> Error: Failed to install perl due to CannotGrowString: Cannot replace b'/cvmfs/mu2e.opensciencegrid.org/packages/perl/5.38.0/linux-almalinux9-x86_64_v2-gcc-11.4.1-5gvcjfeptnu6tfyg7dbfjjb76mk5moaz' with b'/cvmfs/mu2e.opensciencegrid.org/packages2/perl/5.38.0/linux-almalinux9-x86_64_v2-gcc-11.4.1-5gvcjfeptnu6tfyg7dbfjjb76mk5moaz' because the new prefix is longer. To fix this, compile with more padding (config:install_tree:padded_length), or install to a shorter prefix.

Solution is to remove these builds from the cache and re-index it

ssh products@fifeutilgpvm03.fnal.gov
cd rlc_tmp
mv /spack_cache/mu2e/build_cache/linux-almalinux9-x86_64_v2/gcc-11.4.1/perl-5.38.0 .
mv /spack_cache/mu2e/build_cache/linux-almalinux9-x86_64_v2-gcc-11.4.1-perl-5.38.0-5gvcjfeptnu6tfyg7dbfjjb76mk5moaz.spec.json.sig .
