Been there already. The formmail.cgi issue is one of the things they borked on the latest EDGE update
Roll back to release and the problem will be fixed.
I spent 2 days looking for the issue and logged a ticket on it but did not get a solution in time so I rolled back to release
This is the ticket I submitted. Looks like they screwed up the perl @INC on the compiled FormMail.cgi as its looking for perl 5.6.2. Even doing a symlink of 5.8.7 to 5.6.2 will not completely resolve this. The FormMail.cgi is calling a undefined routing in Carp.pm but due to FormMail being compiled I can not look at it to see why its screwed.
FormMail.cgi Has failed after update to latest EDGE and also cpan module::build
is missing C_support which can be fixed by installing perlinstaller
ExtUtils::ParseXS
As you can see by the locate command there is not a 5.6.2 perl on this system
so it can not find the libs
Goto undefined subroutine &Carp::shortmess_heavy at
/usr/lib/perl5/5.6.2/Carp.pm line 110.
