"make deinstall" within /usr/ports/lang - need to recover default language installs

[Rob Navarro]

Hi Chaps,

I typed "make deinstall" within the /usr/ports/lang directory of a
FreeBSD 9.0 and mistakenly lost Perl, Python, Ruby and a whole host of
default compiled languages.

How can I get back to the default FreeBSD default installed language
state (with Perl installed etc)?

Crossing my fingers that I need not re-install the OS...

Kind regards,

Rob
