Build error regarding mf2pt1 with latest texlive (2011) and lilypond 2.14.1

[Marc Payne]

Hi there.

I haven't found any references to this problem on the mailing lists or
elsewhere, so I hope my input is useful.

On my Arch Linux system, fully up-to-date, with the latest texlive in Arch's 
testing repo, I get the following error when trying to build lilypond 2.14.1
from source:

"Sorry, I can't find the 'mf2pt1' preload file; will try 'plain'.This is 
MetaPost, version 1.504 (kpathsea version 6.0.1)"

I am left with an mpost prompt.

To hack around the problem, I had to make a minor change to 
scripts/build/mf2pt1.pl (line 429) in addition to the patch provided by Arch 
(http://goo.gl/5o1xs):

- execute_command 1, ("mpost", "-mem=mf2pt1", "-progname=mpost",
+ execute_command 1, ("mpost", "-mem=../../mf2pt1", "-progname=mpost",

Obviously this isn't a proper fix, but it allowed lilypond to compile and run.

If you need more info, I'll be glad to provide it.

Thanks! :)
