spack external find errors out on unreadable path #38733
Description
Steps to reproduce
I ran spack external find and it errored out as a path is unreadable by users:
$ spack external find
==> Error: [Errno 13] Permission denied: '/usr/local/lib'
$ ls -ltr /usr/local/ | grep lib
drwxr-xr-x 4 root root 4096 Aug 5 2021 lib64/
drwx------ 9 root root 4096 Aug 27 2022 lib/It looks like spack external find assumes /usr/local/lib is readable.
I naively tried --exclude /usr/local/lib but --exclude is for excluding packages.
Error message
I also ran:
spack --debug --traceback external findThe ending traceback is:

I can provide the full debug if needed, but it is...long!
