fatal: Unable to create '/export/home/buildbot-unstable10s/slave/wget-solaris10-sparc/build/.git/modules/gnulib/index.lock': File exists.

If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
process is running and remove the file manually to continue.
