[Tilesathome] pngnq

[Sabine Sagner-Weigl]

Hi!

When starting a client I get the error message:
 ! Can't find pngnq (using "pngnq")
 
But pngnq is installed:
pngnq is /usr/bin/pngnq

During processing the tile I get error messages like:
[#7  76% tile] ColorQuantizing tile_14_9820_6531.png with "pngnq" failed  
or      
[#1  48% maplint] ColorQuantizing maplint_16_34842_22407.png with "pngnq" failed 

What can I do? 
Thank you!
