Well, not everything, but everything related to files linked against older 
versions of libperl.

Were all these files found in a directory belonging to an older version of 
perl?  For example, the current perl is /usr/lib64/perl5, so you'll have files 
like:

/usr/lib64/libperl.so.5.40.0

and symlinks to it from your perl5 directory, e.g.:

~ $ ls -la /usr/lib64/perl5/5.40/x86_64-linux/CORE/libperl.so.5.40
lrwxrwxrwx 1 root root 29 Jan 19 11:55 /usr/lib64/perl5/5.40/x86_64-linux/
CORE/libperl.so.5.40 -> ../../../../libperl.so.5.40.0

If the files you're concerned about are under a directory belonging to a 
previous version of perl , e.g. perl4, then you can remove the lot after you 
run perl-cleaner.

There was some old script to remove cruft, but I have never used it.  I think 
as Gentoo matured over the years, files left behind when you uninstall a 
package have become less likely.

There is 'qfile -o ...'  you can use with 'find' to identify any orphan files 
left in your system, but it assumes you know what types of files to search 
for, e.g. "*.la".  Have a look at the examples in the man page, to see how it 
can be used.
