Interesting.  The error message says “rebuild the format”, so it’s 
possible that we actually need to do that.

If you look at the definition of texlive-latex-base, we’re 
building a few formats in the “build” phase.  Actually, you’ll see 
all the formats that we *don’t* build, but what’s left includes 
“pdflatex”.  It’s possible that we need to change this slightly to 
ensure that the hyphenation patterns are actually found.  My guess 
is that when we build these formats, TeX is not aware of the 
hyphenation patterns, even though they are in the build 
environment.
