@3v1n0 - what version of the Cabal library is present in this build?

[3v1n0]

From the logs install is cabal-install=2.4.0.0-2build3 but not sure if that mismatches with the actual cabal.

The build happened in a build machine, so if you need further details that logs don't provide, let me know all you need and I can reproduce it locally.

[jtdaugherty]

Can you find the version of the Cabal library in the build log? That is often different from the version of the cabal-install tool.

[3v1n0]

Library version seems to match though:

❯ cabal --version          
cabal-install version 2.4.0.0
compiled using version 2.4.0.1 of the Cabal library
