make check stops in the middle

I tried to run make check, but it hangs on me. The flying dots just stop, always in the same place.

All prerequisites are installed, except for cvs, and I did check that I can ssh into localhost.

make check 
golint -set_exit_status ./...
shellcheck -f gcc extractversion.sh repobench test/fi-to-fi test/liftcheck test/singlelift test/svn-to-git test/svn-to-svn test/delver test/*.sh test/*test

workflow-svn-git.sh runs to the end fine, if I run it manually

Any idea?
