Deb11 built against liffi8 but should be built against libffi7
Henning Thielemann reports:
I try
https://downloads.haskell.org/ghc/9.4.1-rc1/ghc-9.4.0.20220721-x86_64-deb11-linux.tar.lz
on Debian 11.
$ /usr/local/ghc-9.4.0/bin/ghc --version /usr/local/ghc-9.4.0/lib/ghc-9.4.0.20220721/bin/ghc-9.4.0.20220721: error while loading shared libraries: libffi.so.8: cannot open shared object file: No such file or directory
Debian 11 seems to support only libffi7:
$ dpkg --list "libffi"
ii libffi-dev:amd64 3.3-6 amd64 Foreign Function Interface library (development files) un libffi4-dev (keine Beschreibung vorhanden) ii libffi7:amd64 3.3-6 amd64 Foreign Function Interface library runtime ii libffi7:i386 3.3-6 i386 Foreign Function Interface library runtime
I think this dependency is new and was not present in the Alpha releases.
Also many directories have no read and cd permissions for 'other' users.
