It does actually look like you have two perls installed.
Look at your whereis output, /usr/bin/perl vs /usr/local/bin/perl
You can verify this further by doing /usr/bin/perl -V and /usr/local/bin/perl -V
I had a similar problem after a release-upgrade on my ubuntu-server.
Unfortunately my only solution was to reinstall the system.
$ ls -l /opt/admin/bin/perl /usr/local/bin/perl /usr/bin/perl
lrwxrwxrwx 1 root root 13 Apr 10 16:38 /opt/admin/bin/perl -> /usr/
-rwxr-xr-x 2 root root 19208 Dec 16 2011 /usr/bin/perl
lrwxrwxrwx 1 root root 13 Apr 27 14:01 /usr/local/bin/perl -> /usr/
