ghc @9.6.3: UndefinedError("'style' is undefined")

[breiter (Brian Reiter)]

GHC itself compiles successfully but the documentation build step fails which causes the entire port to fail.

This is a problem for ghc @2.6.2 and the @2.6.3 pull request.

I confirmed that sphinx 6.2.1 does work and allow the ghc port to build and install by using pip tp install sphinx 6.2.1 over the py310-sphinx @7.2.6_0 package.

sudo port install py310-sphinx
sudo -H pip-3.10 install Sphinx==6.2.1

And then uninstalling the pip package and re-installing py310-sphinx so the package database is not insane after installing ghc.

sudo -H pip-3.10 uninstall Sphinx==6.2.1
sudo port uninstall -f py310-sphinx
sudo port uninstall py310-pip
sudo port clean py310-sphinx
sudo port install py310-sphinx
sudo port setunrequested py310-sphinx

Update rdt-theme to latest upstream version.

This latest commit apparently fails to address the issue: ​https://github.com/macports/macports-ports/commit/99d3a312a2d08a212782999e0db71afa79e350ad#diff-c7968cfa7dd4491c4f36b05d17922247eee14b20e9a0abd8e2a05879af62c173

I recommend either rolling back to the latest version of ghc that builds and waiting for upstream to address this issue, or commenting out the Portfile commands that build the documentation.

the latest commit fixed the ghc 9.6.3 build on almost every system, according to the buildbot

one or two fails to sort out
