[Lazarus] Can't call the resource compiler

[Vojtěch Čihák]

Hi,
 
I have often following message when I try to rebuild Lazarus from IDE:
 
lazarus.pp(167,1) Error: Can't call the resource compiler "/usr/local/bin/fpcres", switching to external mode
 
It happens ~last week with trunk: Lazarus 1.9.0 r58270M FPC 3.1.1 x86_64-linux-qt (or qt5).
 
There's no specific error message, caret is on the last line of lazarus.pp. Console also didn't show anything unusual; fpcres is on its place.
 
How can I solve it?
 
Thanks,
 
V.
