[pve-devel] Error when build i18n file

[Claudio Ferreira]

Hi

I did a lot of translations and I want to try it in my env. I followed this
instructions[1] and returned this error:
$ ./po2js.pl -t pve pt_BR.po > pve-lang-pt_BR.js
Use of uninitialized value in concatenation (.) or string at ./po2js.pl
line 91.

Unfortunately, google can't help me.
Some tip?

Regards,
Claudio Ferreira
