installing needed file within LilyDev

[David Nalesnik]

Hi all,

I'm trying to compile the latest master within LilyDev, and I'm
running into a problem when I try to prepare the build directory.  I
get the following error:

ERROR: Please install required programs:  lh CTAN package
(texlive-lang-cyrillic or texlive-texmf-fonts)

Can someone give me pointers on what to do at this point?  I'm unsure
where the needed files ought to go and how to get them installed there
correctly...

Thanks so much,
David
