Your best bet is to look inside the config script (it's probably shell script) to see where it's looking for perl, and then creating that symlink appropriately. For example, it may only look at /usr/bin/perl, and you may have installed perl as /usr/local/bin. It's hard to tell.
Also, when you're posting code or output, wrap it in <code>...</code> tags, or, for the lazy, in <c>...</c> tags, that way they display properly. This is part of the Writeup Formatting Tips that you see at the bottom of the screen after hitting the preview button. Thanks.
