I am trying to package ‘chicken-begin-syntax’, it requires version 0.2.1
of ‘module-declarations’, which I have created a Guix package for (only
exists on my local branch).  However, when compiling
‘chicken-begin-syntax’, ‘chicken-install’ complains about an outdated
version of ‘module-declarations’, even though it’s not outdated.

Removing this restriction makes it build.

The content of ‘begin-syntax.egg’:

--8<---------------cut here---------------start------------->8---
((synopsis "Convenience macro for inline syntax expansion")
 (author "Evan Hanson")
 (license "BSD")
 (category lang-exts)
 (dependencies matchable)
 (test-dependencies srfi-1)
 (build-dependencies (module-declarations "0.2.1"))
 (components (extension begin-syntax (csc-options "-X" "module-declarations"))))
--8<---------------cut here---------------end--------------->8---

Build error message:

--8<---------------cut here---------------start------------->8---
starting phase `build'
The following installed extensions are outdated, because `begin-syntax' requires later versions:

  module-declarations (0.0.0 -> 0.2.1)

Do you want to replace the existing extensions? (yes/no/abort)

I also tried passing the ‘-force’ and ‘-verbose’ flags to
‘chicken-install’, now it complains about ‘module-declarations’ not
being cached.   ¯\_(ツ)_/¯
