Bug#991241: lrx-proc: command not found

[Pelle]

Package: apertium-swe-dan
Version: 0.8.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

When trying to use Apertium with the Swedish-Danish pair, I get the 
following error at startup, and no translation happens:

$ apertium dan-swe
/dev/fd/63: line 1: lrx-proc: command not found
hallo verden

Apertium works fine with other language pairs, like English-Esperanto:

$ apertium en-eo
hello world
hala mondo
