we noticed an additional issue with ExtUtils::Depends. When building package
xacobeo the linking order was random due to an unsorted iteration over the keys
of a perl hash.

The attached patch includes Reiner's initial patch and the fix to this
additional problem.

We also submitted the issue to upstream as part of the same bug Reiner opened.

We maintain a git repository including this patch as part of the experimental
reproducible build effort. So alternatively you can also clone from:

https://anonscm.debian.org/git/reproducible/libextutils-depends-perl.git

or look at it in the web interface at:

https://anonscm.debian.org/cgit/reproducible/libextutils-depends-perl.git/

Cheers, akira
