That's one of the main features of the new font
installation strategy, introduced in 1.5.42.
Some details can be found in 
Documentation/misc/fontinstallation.

One way to keep the font lilypond installations
completely independent is to make sure that you
have write permission in the directory
$prefix/share/lilypond/1.x.xx/fonts/pk/
for both your installations (one way is to 
let it be a soft link to soem directory in /tmp/.
Of course these should be different for the two
Lilypond versions).
Another method is to explicitly set the
environment variable VARTEXFONTS to point to some
writable directory, again using different 
directories for the two versions.

Some more information on the general mechanisms
that play games here, can be found in the comments
of the file `kpsewhich texmf.cnf` and in the 
info documentation of kpathsea.
