Commit 1764ea2b0a introduced changes to libxslt
in an awkward way to avoid re-builds on Linux. This patch has been simplified
during this merge.
libxslt has optional dependencies which may be found in /usr or
/usr/local on platforms that have a native stdenv. With those features
enabled, the build generated binaries that depend on libraries outside
of the store. In this particular case, the NixOS channel had binaries
for FreeBSD that depended on libgcrypt, apparently because that packages
happens to be installed outside of Nix on the build machine. On other
machines, however, those binaries failed with unresolvable references.

they need an older version of test-framework
using jailbreak didn't work in this case so for now, disabling tests
is the easiest solution until upstream upgrades its test-framework
This predicate filters out packages that weren't created by the Cabal builder.
Doing that greatly reduces the likelihood of file collisions in the generated
environment, because Haskell packages tend to have a lot of propagated build
inputs.
For example, both zeromq 2.x and 3.x use the same names for their header files.
Users of haskell-zeromq don't need those headers, so we just don't include them
in the generated environment to avoid the collision that would otherwise occur
when haskell-zeromq 2.x and 3.x are installed into the same environment.
