I am sorry to bug you again. A lot of GNOME programs which include
gnome-doc-utils exhibit this behavior and therefore it would be very
cumbersome to change all calls to be able to cross compile them.

LinuxTag 2011 is going to start on Wednesday. If you could propose
generic solution on how to determine the data directory when cross
compiling this would be great, since I could bring up this problem and
discuss proposed solutions directly with some developers.


Thanks,

Paul
