Subject: [PATCH] gnu: b4: Fix setup.py version incompatibility.
Date: Mon,  1 Mar 2021 20:51:58 -0500

Following the update of python-requests to 2.25.0, b4 fails at runtime with a
pkg_resources.ContextualVersionConflict exception.  This has been addressed
upstream.  Temporarily apply the upstream fix.

* gnu/packages/patches/b4-loosen-version-identifiers.patch: New patch.
* gnu/packages/version-control.scm (b4): Apply it.

+Subject: Loosen compatible release identifiers for install_requires
+
+The install_requires entries use a compatible release operator.  As an
+example, "requests~=2.24.0" maps to a requirement of ">= 2.24.0 and ==
+2.24.*".  With the current version of requests (2.25.1), this leads to
+a ContextualVersionConflict failure at runtime.
+
+Allowing only Z to tick in version X.Y.Z seems unnecessarily strict
+unless there are known problems with a particular release, and it
+makes it more difficult for distributions to package b4.  Drop the
+trailing digit from all of the version identifiers, allowing both Y
+and Z to increase.

Not sure how I forgot I had this waiting for me. I changed the
substitution from "\\.0'" to change the ~= to >= and pushed it.
