Hi Murray,

I suspect these are different problems for each package. Some of the packages 
you mention (CddInterface, xgap and NormalizInterface) connect to external 
programs.

Unless you specifically need one of these packages, I would not worry about the 
issues. If you do need one of the packages, then you should read the 
documentation for that package, and if that does not help you reach out to 
authors (or file an issue on github, if the package is hosted on github)

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

I’m trying to get GAP 4.11.0 installed uner macOS Catalina 10.15.7 but am 
getting several packages seeming to complete their configuration OK but then 
failing to build:

CddInterface-2020.01.01
xgap-4.30
semigroups-3.2.3
NormalizInterface-1.1.0
guava-3.15
anupq-3.2.1

The errors seem to be for different reasons among the various packages. 

Is there some systematic, common problem here, rather than different underlying 
causes for the different packages?

Examples of the build errors:

CddInterface-2020.01.01
