[tex-live] No cont-nl.fmt in Tex Live 2013

[Peter Van Kranenburg]

Dear list,

In Tex Live 2013 (mac) I can't compile context documents with Dutch 
commands:

----test-nl.tex-----
\starttekst
Dit is tekst.
\stoptekst
--------------------

----command line----
pvk$ texexec test-nl.tex
This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013)
  restricted \write18 enabled.

kpathsea: Running mktexfmt cont-nl.fmt
I can't find the format file `cont-nl.fmt'!

pvk$ locate cont-nl.fmt
/usr/local/texlive/2011/texmf-var/web2c/pdftex/cont-nl.fmt
--------------------

Apparently cont-nl.fmt is needed, but the only file with that name in my 
file system seems to belong to Tex Live 2011.

In Tex Live 2012 everything was OK.

Could anyone advise me what to do? How to build cont-nl format? I 
couldn't find this in the context documentation either.

Thanks

Peter van Kranenburg
