[GAP Forum] GAP 4.11.0, macOS 10.15.7, Several packages not building

[Russ Woodroofe]

Dear all,
We troubleshot this off-list.  The problem turned out to be with the oh-my-zsh addon for zsh, which apparently breaks gap. 

It might be worthwhile to document this conflict somewhere in the install documentation for GAP, as it looks like it'll be a problem for anyone using zsh with this add-on.  
Best,

  --Russ

CddInterface and NormalizInterface seem (to me) to be tricky to build, with quite a few requirements etc.  Not sure offhand about anupq or semigroups.
