Well, I guessed wrong, but I use exec in place of the dot, and it works
fine.

This doesn't address the problem, environment variables can be handled
native, but alias assignments can not. Also, you can't export aliases.
However, system forks a child, so the export only affects the child, this
doesn't get back to the parent. I think the problem was changed to make the
answer easy.
The other suggestion of returning the alias as:
$aliascmd = `aliasProg.pl`;
Still doesn't address the problem. So now you know the alias command to
run, but, how do you run it, maybe:
system("$aliascmd");
No, that won't work, because the alias command is running in a forked child.
I still think you need to:
exec("aliasProg.pl");
Then, at the end of aliasProg.pl, exec("$shell");
The $shell variable doesn't have to be hardcoded, it can be read from the
environment (at least on my system).
