Hi Francois,

   I am not surprised that the file debug_gap.vim is not installed in your  
system. The installation of this file is handled by the vim-syntax  
useflag. This useflag also handles the installation of other useful vim  
files.

   One option would be to introduce the debug useflag for gap and install  
this debug_gap.vim file if both vim-syntax and debug flags are on. And,  
during the src_prepare apply the patch to debug_gap.vim. I can provide you  
an updated ebuild if you so desire.
