Subject: | Invalid regexp syntax used in egrep call |
Makefile.PL has this line:
my @locales = `locale -a | egrep -i 'UTF\-?8' | egrep '^(?:$loc)'`;
The pattern of the 2nd egrep call looks wrong, (?:...) is a perl extension and not available in standard grep. Probably you have to remove the "?:" bit.
