Makepkg localization quirks

Question

I don't recall changing anything in my localization settings, I want all the messages in English, but for some reason some of them appear in Polish.
$ locale
LANG=pl_PL.UTF-8
LC_CTYPE="pl_PL.UTF-8"
LC_NUMERIC="pl_PL.UTF-8"
LC_TIME="pl_PL.UTF-8"
LC_COLLATE=C
LC_MONETARY="pl_PL.UTF-8"
LC_MESSAGES=C
LC_PAPER="pl_PL.UTF-8"
LC_NAME="pl_PL.UTF-8"
LC_ADDRESS="pl_PL.UTF-8"
LC_TELEPHONE="pl_PL.UTF-8"
LC_MEASUREMENT="pl_PL.UTF-8"
LC_IDENTIFICATION="pl_PL.UTF-8"
LC_ALL=
I used bold to show the messages in Polish:

I aborted and tried again - everything was in English now.
I've seen such behavior once or twice before in the past couple days, any idea how to fix / debug it?

Answer 1

Here it is, the first line returned nothing while the second one run for ages and now I have a long gray beard - hope it was worth it ;P
