[tlbuild] Bug#767967: Metapost: With prologues=1, produces lots of duplicate fontmap entries

[Norbert Preining]

Hi Taco,

there seems to be small problem with double inclusion of psfonts.map
again/still ...

Although in 1.800 announcement there was written something about fixing this,
the problem is still present as far as I see in current TeX Live svn,
which is also in Debian, see message below.

Is there anything we can do to fix that?

Thanks a lot

Norbert
