Package: libfile-scan-perl
Version: 1.43-2
Severity: wishlist
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: randomness timestamp
X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
This package can't currently be built reproducibly
because the code generated by Makefile.PL embeds
a timestamp and uses unsorted hash keys.
Two patches attached. The test suite is very minimal,
so eyeballs would be welcome.
