Bug#585678: perl: Performing a binNMU of perl causes a silently broken build

thanks

Hi,

I can reproduce this.  After an binNMU the "install*" variables in
Config_heavy.pm include the build directory.  The attached patch
disables pattern meta-characters in the substitution.  It should be safe
as long as neither ! nor \E are included in the build directory.

Regards,
Ansgar
