This comes from fontconfig, I think.  Do you probably have added the
whole TeXLive font tree to fontconfig?  This makes fontconfig slooow,
at least on my GNU/Linux box...

The question is whether 2.5 minutes is expected for creating the font
cache.  If you say

  fc-list

on the command line, how many fonts are listed?  On my box, due to
TeXLive, I have more than 9000 fonts...

Another test is to find out how long

  fc-cache --verbose --force

needs for building the whole cache – I think something similar to this
is what lilypond triggers if run the first time.
