>Description:
After an upgrade to pkgsrc-2010Q3, I have problems with mkvtoolnix. First it 
seems to be very picky about LANG/LC settings. It does not like e.g. 
LANG=en_US.UTF-8.

But when all locale settings are removed, I still cannot run mkvmerge. It gets 
stuck at 0% when I'm muxing e.g. subs to an MKV file:

mkvmerge -o new.mkv Foo.mkv --sub-charset 0:ISO-8859-15 --language 0:swe 
--default-track 0:yes --compression 0:none Foo.srt 
mkvmerge v4.3.0 ('Escape from the Island') built on Sep 14 2010 20:33:34
'Foo.mkv': Using the Matroska demultiplexer.
'Foo.srt': Using the SRT subtitle reader.
'Foo.mkv' track 1: Using the MPEG-4 part 10 (AVC) video output module.
'Foo.mkv' track 2: Using the AC3 output module.
'Foo.srt' track 0: Using the text subtitle output module.
The file 'new.mkv' has been opened for writing.
Progress: 0%

>How-To-Repeat:
Upgrade to pkgsrc-2010Q3 or pkgsrc-current. Install mkvtoolnix-4.3.0nb1. Run 
mkvmerge to e.g. mux in a subtitle track to a MKV file.
