Very strange problem...

I really don't understand this...
I have an ebuild for epsxe (playstation emulator)..
After "ebuild unpack" I check /var/tmp/portage/epsxe-1.5.2/work and it 
contains the correct, working binary.
After "ebuild install", the epsxe binary is in 
/var/tmp/portage/epsxe-1.5.2/image/opt/epsxe, but it is only 92 bytes and 
contais ".ELF............".. The first 92 bytes of the original binary that 
is.. It doesn't matter if I use insinto;doins, dobin, cp or mv in 
src_install.. It still gets truncated to 92 bytes...

Here is the ebuild (dobin ${FILESDIR}-line commented so you can try it):
