Good to hear that it won't affect pure packages.

But, sadly, it is not enough: In nixos there are no environment
varibales set for compilation that would point to the "correct" non-pure
locations.

For me, just running ldconfig already raises an error:
$ which ldconfig
/var/run/current-system/sw/sbin/ldconfig

$ ldconfig 
ldconfig: Can't open configuration file /nix/store/vxycd107wjbhcj720hzkw2px7s7kr724-glibc-2.12.2/etc/ld.so.conf: No such file or directory
ldconfig: Can't create temporary cache file /nix/store/vxycd107wjbhcj720hzkw2px7s7kr724-glibc-2.12.2/etc/ld.so.cache~: Permission denied

I am not deep enough into LD_LIBRARY_PATH, LDFLAGS, CFLAGS to know what
to set. Will now read up what needs to be done.

Still greatful for any hints.

My intention is not to live with a dirty system, but simply to be able
to stay on nixos while getting my work done right now. And therefore be
able to contribute to nixos and sooner or later reach the state of a
pure system again.
