emacs-guix throwing errors

[Brett Gilio]

Hi all. I am hoping the maintainer of emacs-guix will see this:

Whenever I try to search for a package, or perform any of the routine
guix commands using the emacs-guix interface, I am getting this error.

guix-geiser-eval: Error in evaluating guile expression: ERROR: In procedure 
string-append:
In procedure string-append: Wrong type (expecting string):
#<<search-path-specification> variable: "GHC_PACKAGE_PATH" files:
("lib/ghc-8.0.2") separator: ":" file-type: directory file-pattern:
".*\\.conf\\.d$">

The specifics of the string seem to change based on what I am trying to
do, but regardless it does not work and I have to perform those commands
using the command line.

Any ideas?
