Guile cannot find libcurl

[Sascha Ziemann]

I tried to install akku, but Guile fails to load libcurl. I have no idea
why. Can anybody imagine what is going wrong here?

To start developing in the new project, type this in your shell:

 cd nix
 akku install
 .akku/env

Some implementations may require small adjustments to run R6RS programs
(e.g.
guile -x .guile.sls -x .sls). See the manual for your implementation.

$ cd nix
$ akku install
