issues building gnutls from git on Ubuntu 12.04

[Patrick Pelletier]

On Ubuntu 12.04, I'm attempting to build gnutls from git.  I'm on the  
head of the gnutls "master" branch, and "git status" shows I have no  
files modified, and yet when I do "make bootstrap", autopoint  
complains that I have modified files:

ppelletier at patrick64:~/src/gnutls$ make bootstrap
for f in po/*.po.in; do \
		cp $f `echo $f | sed 's/.in//'`; \
	done
mv build-aux/config.rpath build-aux/config.rpath-
autopoint
autopoint: File ABOUT-NLS has been locally modified.
autopoint: File po/Makefile.in.in has been locally modified.
autopoint: File po/Rules-quot has been locally modified.
autopoint: *** Some files have been locally modified. Not overwriting  
them because --force has not been specified. For your convenience, you  
find the local modifications in the file '/tmp/gtuXtRkI/autopoint.diff'.
autopoint: *** Stop.
make: *** [autoreconf] Error 1
ppelletier at patrick64:~/src/gnutls$

 From the message, it sounds like perhaps I should specify "--force",  
so I edited the line in cfg.mk that invokes autopoint to invoke it  
with "--force".  This seems to fix the problem, although I'm curious  
if this is something I should have to do, or if it indicates some  
deeper problem.

Anyway, with this change, the "make bootstrap" gets much further, but  
eventually fails with:

configure: creating ./config.status
config.status: error: cannot find input file: src/libopts/Makefile.in
make: *** [bootstrap] Error 1

And I'm not sure what to do about that one.  Here are the versions of  
various things that I have installed, although they should just be the  
standard versions that come with Ubuntu 12.04:

Thanks for any advice!
