I have a nightly job which fetches the latest version of GHC
from the anoncvs archive and attempts to build it from
clean (using the
version of the last successful build). However for the last
3 nights there has been a problem, because the build comes to
a halt (lasting for over 6 hours and perhaps for ever)
when trying to compile PosixProxEnv.lhs. What is very puzzling
is that when I kill everything and try to gmake all again, from the
command line, it works fine. Any idea what is going on?
Here is the last output to stdout:
----

And here is the last output to stderr:

So nothing particularly remarkable that I can see - what is going on?
