I have this exact same problem. Carried out an upgrade from Smartor and everything is running smoothly except personal galleries are causing a few issues.
I have the same problem that the module isn't showing up in the User CP, have you found a solution?
I completed (checked, and rechecked!) all installation steps! Is this step missed in the upgrade from Smartor and only included in the standard base install?
It is missing from the install.xml file.. so should this be flagged as a bug?
Need to be copied over (install.xml only covers ACP, not UCP).
From there you can add the module using -Aministration Control Panel -> System -> User Control Panel -> select 'Manage Personal Albums' -> Add Module
