[tlbuild] Broken TL build

[Mojca Miklavec]

Dear Karl & Luigi,

the TL build is broken again:

https://tug.org/svn/texlive?view=revision&revision=61644

CWEBINPUTS=.:../../../texk/web2c/pmpostdir AM_V_P=: /bin/bash
./tangle-sh pmp-tangle ./ctangle pmp pmp
tangle-sh: CWEBINPUTS=.:../../../texk/web2c/pmpostdir
TEXMFCNF=../../../texk/web2c/../kpathsea ./ctangle pmp pmp
! Change file entry did not match. (l. 21 of change file)
#define metapost_version "2.01" (Pardon me, but I think I spotted
something wrong.)
Makefile:21930: recipe for target 'pmp-tangle' failed
make[5]: *** [pmp-tangle] Error 1
