Apologies for bug reporting here, but thought I might as well. My current banner is:
$ pdflatex -version | grep 'TeX Live'
pdfTeX 3.14159265-2.6-1.40.15 (TeX Live 2014)
The problem seems to be described in Printing sentence in ancient Greek – comp.text.tex, and in my case stems from here: Getting Texlive version in pdflatex?; regardless of which example I try, say:
documentclass{article}
defgettexliveversion#1(#2 #3 #4#5#6#7#8)#9relax{#4#5#6#7}
edeftexliveversion{expandaftergettexliveversionpdftexbannerrelax}

The starting verse of the Iliad is
begin{quotation}greektext
Μῆνιν ἄειδε, θεά, Πηληιάδεω Ἀχιλῆος
end{quotation}
and it's really great.
end{document}
… it fails with:
Package babel Warning: No hyphenation patterns were preloaded for
(babel) the language `greek' into the format.
(babel) Please, configure your TeX system to add them and
(babel) rebuild the format. Now I will use the patterns
(babel) preloaded for english instead on input line 44.

The comp.text.tex thread actually mentions:
Actually, to get this far I edited
/usr/share/texlive/texmf-local/texmf-compat/tex/latex/greek.ldf
replacing
ifxl@monogreek@undefined
adddialect@monogreek 0fi
ifxl@ancientgreek@undefined
adddialect@ancientgreek 0fi
by
ifxl@monogreek@undefined
adddialectl@monogreek 0fi
ifxl@ancientgreek@undefined
adddialectl@ancientgreek 0fi
…
The second version has l@monogreek in the second line (for @monogreek),
and a similar change in the fourth line.
After the change my problems go away.
For me, that snippet is in /media/texlive/2014/texmf-dist/tex/generic/babel-greek/greek.ldf, and contains:
...
ProvidesLanguage{greek}
[2014/09/18 v1.9b Greek support for the babel system]
%% File `babel-greek.dtx'
...
ifxl@greek@undefined
@nopatterns{greek}
adddialectl@greek 0fi
ifxl@monogreek@undefined
adddialect@monogreek 0fi
ifxl@ancientgreek@undefined
adddialect@ancientgreek 0fi
Clearly, it should be adddialectl@monogreek, not adddialect@monogreek as it is; and indeed, when I make that change as well, the document compiles just fine.
The thing is this: I installed TexLive from scratch (install-tl), tried to compile the given MWE, it fails with given error – had to hack babel-greek/greek.ldf as described to get it to compile. So, there’s either faulty code in greek.ldf and it’s a bug — or I miss some package, and Latex cannot tell me which with the usual “file not found” message. Since no one else can reproduce this error, it is probably not a bug – but how do I find what I am missing, then?
