The attached versions.scm has been generated using `guix import hackage
versions` and specifying that I want to build it with `#:haskell ,ghc-8.8`.
Upon building, I get the error posted here: http://paste.debian.net/1203119/
I'm not entirely sure what the problem is, but it seems like when another
version of ghc has been specified, dependencies built with another version of
ghc no longer work.

(description
"A library for parsing and comparing software version numbers. We like to give version numbers to our software in a myriad of ways. Some ways follow strict guidelines for incrementing and comparison. Some follow conventional wisdom and are generally self-consistent. Some are just plain asinine. This library provides a means of parsing and comparing /any/ style of versioning, be it a nice Semantic Version like this: . > 1.2.3-r1+git123 . ...or a monstrosity like this: . > 2:10.2+0.0093r3+1-1 . Please switch to <http://semver.org Semantic Versioning> if you aren't currently using it. It provides consistency in version incrementing and has the best constraints on comparisons. . This library implements version @2.0.0@ of the SemVer spec.")
