| Subject: | Sub::Uplevel might be too old |
Have just tried to upgrade Data::ICal to 0.13. Unfortunately several
tests kept failing. I tried with 0.12 and 0.11 and the result was the
same. Looking closer the error was within Sub::Uplevel complaining about
an undefined value. Just on the off chance I upgraded Sub::Uplevel
(0.14) and tried to upgrade Data::ICal again and it worked perfectly.
So you may want to add Sub::Uplevel as a prerequisite in your
Makefile.PL with a specific version to ensure it gets a more recent
version. Unfortunately I didn't check which version I had previously
installed, but 0.14 seems to work without a problem.
