[Nix-dev] builder for ‘*.drv’ failed to produce output path ‘*’

[Tinker]

Thanks, that worked.

If I install it now and run `pgloader` I am getting (somewhere in sbcl):

Error opening shared object "libsqlite3.so.0":...

It works if I manually set the LD_LIBRARY_PATH

export LD_LIBRARY_PATH=
/nix/store/nn4srgg3f8hvb6x30df058kl67ar3wr9-lisp-cl+ssl-git-20141113/lib:/nix/store/w0ml3zjnqawcw2dlamn9q3pilplmgryi-openssl-1.0.1p/lib:/nix/store/z35b0yjmrhhl0cfxrkymf4387i3pjkjm-sqlite-3.8.11.1/lib:/nix/store/byk49dzimn7yxyjk16674yd54n6krwn3-freetds-0.91/lib

How do other utils typically deal with this?
Does the user need to do this himself after installing with nix-env?
And if so, how to find out the paths (I could find them out by opening
a nix-shell and inspecting the variable)?
Or is this something that should rather be done through a shell.nix or
an environment?
