Unable to install packages in GAP

I need to install the package itc (https://www.gap-system.org/Packages/itc.html) in GAP. I installed packages gap and gap-packages, the latter contains the package PackageManager. But I have troubles with any package installation:

$ gap

There is no BuildPackages.sh in my system. How can I solve this problem?

Re: Unable to install packages in GAP

Both the itc and the xgap package are already part of the gap-packages package (and probably all the packages, FWIW)

It does look like the package does not explicitly provide the BuildPackages.sh for reasons I'm unsure of, however all of the packages are built as part of the gap-packages package.

Re: Unable to install packages in GAP

Thanks you, you are right. I found the xgap executable file. But why I can't start it?

$ /usr/lib/gap/pkg/xgap-4.30/bin/x86_64-unknown-linux-gnu-gcc/xgap
Panic: cannot establish communication with gap.%
