Hey,

Thanks for your quick response. I have a few questions:

* What do you mean by "install it in your profile"? Do you mean I should
add the lines for Guile in my ~/.profile?

* How or where does Guix tell me which path I have to set? I moved the
Guile stuff to my ~/.profile and ran a few Guix commands (install a
package, upgrade packages, pull), but it did not mention anything about
my path.

Thanks for you help,

Zelphir
