If I understand correctly, this patch solves the error.

Without extractpdfmark,
each eps file has relative font path from `lilypond-datadir`.
e.g.
```
%%BeginProlog
/lilypond-datadir where {pop} {userdict /lilypond-datadir
(/path/to/lilypond/build-without-extractpdfmark/out/share/lilypond/current) put
} ifelse
%%BeginFont: Emmentaler-20
lilypond-datadir (/fonts/otf/emmentaler-20.otf) concatstrings (r) file .loadfont
%%EndFont
```
Then, `output-distance.py` invoked gs with commandline option
`-slilypond-datadir=input/regression/out-test-baseline/share/lilypond/current`.
It specified `lilypond-datadir` as relative path
from `/path/to/lilypond/build-without-extractpdfmark`.
However, current directory was
`/path/to/lilypond/build-without-extractpdfmark/input/regression/out-test-baseline/share/lilypond/current`
because
http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=blob;f=scripts/build/output-distance.py;h=ba787931a5edb6f1f2f46e6c53e851241ba4b9d1;hb=HEAD#l648
changes current directory.
Since current directory was different from the origin of the relative path,
gs could not find the font file.
My patch shown above fixes the wrong relative path specification.
On the other hand, with extractpdfmark,
each eps file has absolute font path.
e.g.
```
%%BeginProlog
/lilypond-datadir where {pop} {userdict /lilypond-datadir
(/path/to/lilypond/build-with-extractpdfmark/out/share/lilypond/current) put }
ifelse
%%BeginFont: Emmentaler-20
(/path/to/lilypond/build-with-extractpdfmark/out/share/lilypond/current/fonts/otf/emmentaler-20.otf)
(r) file .loadfont
%%EndFont
```
In this case,
even if `lilypond-datadir` is specified as such a wrong relative directory,
gs can find the font file.
However, I think absolute font path in eps is undesirable behavior.
So, I've created Issue 5467.
