no, but your email camethrough before your question about "__ps";

therefore your emails sounded like: "i have removed an arbitrary file 
from the Gem-sources and now it doesn't work anymore" - which is not 
very surprising :-)

i cannot answer you this, but recently i have modified the build-system 
of Gem a bit, so that all .o files are copiled into the ./Objects folder 
before they are linked.
this is part of an ongoing try, to compile Gem (partly) as single externals.

anyhow, could you do a "make distclean" (and eventually removed all 
traces of .o and .d files in the Gem/src tree) and afterwards do a fresh 
build.
