Trouble installing GAP package `nq` (and hence `hap`) on macOS

[fingolfin]

Getting this with latest GAP.jl master:

Does the mentioned log file give any idea what went wrong?

(I cannot check the macOS version. When I try the same under Linux, I get a few warnings from the compilation step, but the return value is true.)

[fingolfin]

Sorry, I should have mentioned that it works under Linux.

I cannot check the logs because PackageManager deletes them; and it also deletes the failed directory, so I can't debug the output of that either.

I've logged this as a debugging issue two years ago at https://github.com/gap-packages/PackageManager/issues/66 ...

I think it would be great if we had a kwarg debug=true/false for GAP.Packages.install; if set to true we'd instruct PackageManager to not delete the log and package directory. Of course that then also requires a corresponding feature in PackageManager

[fingolfin]

I made https://github.com/gap-packages/PackageManager/issues/66 to help with this debug idea.

Perhaps we can also have debug change the InfoPackageManager info level to 2 or 3 or so

PR for "debug" feature is upcoming. In the meantime, it yielded this:

sigh OK I know in principle how to deal with it.
