The current version of Python fails to build some dependencies, but
pinning the previous version works.
ActivePerl is no longer installable via Chocolatey (neither current
nor older versions) as ActiveState don't provide the downloads
without registration any longer (and even if registered, only
provide the latest, continuously updated version for free users, which
can't match the package manager checksums), see http://disq.us/p/2ipditb
for further discussion.
Replace ActivePerl with StrawberryPerl. StrawberryPerl has other
drawbacks, as it installs a whole C/C++ toolchain as part of it,
and copies of pkg-config tools that can cause package misdetections.
Remove these after installing it, see
https://github.com/StrawberryPerl/Perl-Dist-Strawberry/issues/11
for discussion on the inconveniences of installing it.
