Bug#702847: libdevel-cover-perl: Failure under mod_perl2 due to using $^X

[Martín Ferrari]

Package: libdevel-cover-perl
Version: 0.96-1
Severity: normal
Tags: upstream

Since a few versions ago, Devel::Cover is using $^X to call perl for an ugly
hack to get a default @INC. The problem is that $^X is not always 'perl', under
mod_perl it would normally be 'httpd', but in our case, it is 'apache2'. So
hilarity ensues when this is executed:

execve("/usr/lib/apache2/mpm-prefork/apache2", ["/usr/lib/apache2/mpm-prefork/apache2", "-MData::Dumper", "-e", "print Dumper \\@INC"], [/* 2 vars */]) = 0

The old versions relied on mod_perl-specific environment variables to realise
they were running under mod_perl. The current check ($^X =~ /httpd$/) is pretty
silly.
