Your system time

    real    22m21.918s
    user    13m49.982s
    sys     23m1.702s

suggests something is seriously off on your system.
Perhaps machine is swapping heavily.

If it works that long for you you should be able
to explore the problem as it goes with tools like
'perf top', 'strace' and others.

Build times for purescript on my machine don't
exceed 1 minute.
