ORBit2-2.6.3 Compilation error

[Gavazzi Raphael <gavazzi iap fr>]

Hi,
 
I don't understand the reason of that compilation error (I'm installing 
a Gentoo distribution ebuild for ORBit2)
The directory  
/tmp/portage/portage/ORBit2-2.6.3/work/ORBit2-2.6.3/src/orb/orb-core 
does not contain any corba-defs-common.c
file...
any idea? Thank you  in advance,
Cheers,
Raphael
