That doesn't look right to me. ls does not display dotfiles by default, that requires the -a option or similar. Either you are not running a bare ls (eg. using an alias or function or other wrapper) or something else is going on which you have not explained. Either way, this casts doubt on the following snippet in which you use ls -l to "show" the absence of a dotfile.

Assuming the dotfile absence is real, however, my best guess would be that something in the Catalyst installation has not completed entirely as expected for some reason or another. It is a bit of a beast in terms of dependencies so a snag in any of those could potentially bubble up and cause a problem with the overall installation. Either go through the cpanm logfile to find it or else try installing Catalyst by hand.
