Trying to build a fresh copy of GHC HEAD (at commit ) today failed
for me with this error: 
/u/rgscott/Software/ghc4/libffi/build/missing: line 81: makeinfo:
command not found
WARNING: 'makeinfo' is missing on your system.
You should only need it if you modified a '.texi' file, or
any other file indirectly affecting the aspect of the manual.
You might want to install the Texinfo package:
The spurious makeinfo call might also be the consequence of
using a buggy 'make' (AIX, DU, IRIX), in which case you might
want to install GNU make:
On my Ubuntu machine, I was able to work around the issue by running:
apt-get install texinfo
But I'm not sure if the texinfo requirement was expected or an
unintended side effect of recent libffi changes. Do you know what's
happening here Moritz?
