Errors after CVS *import*

Hey there,
I got a really strange error...
I've checked out a HEAD from GG, did some changes (removed some directories, renamed the exe, etc.) and it all works fine.
Now, I've zipped it, uploaded it to my CVS server, unzipped, and imported with this:

cvs -d /usr/local/arenacvs -z6 import -I ! -I CVS -W "*.mcp -k 'b'" -W
"*.pdf -k 'b'" -W "*.zip -k 'b'" -W "*.icns -k 'b'" -W "*.rsrc -k 'b'" -W
"*.tsb -k 'b'" -W "*.tsw -k 'b'" -W "*.exe -k 'b'" -W "*.dll -k 'b'" -W
"*.ilk -k 'b'" -W "*.hfl -k 'b'" -W "*.gft -k 'b'" -W "*.psd -k 'b'" -W
"*.gif -k 'b'" -W "*.rmf -k 'b'" -W "*.rmx -k 'b'" -W "*.wad -k 'b'" -W
"*.dif -k 'b'" -W "*.ml -k 'b'" -W "*.dsq -k 'b'" -W "*.max -k 'b'" -W
"*.ms3d -k 'b'" -W "*.dts -k 'b'" -W "*.gpk -k 'b'" -W "*.WAV -k 'b'" -W
"*.wav -k 'b'" -W "*.jpg -k 'b'" -W "*.raw -k 'b'" -W "*.ter -k 'b'" -W
"*.png -k 'b'" -W "*.dso -k 'b'" -W "*.exp -k 'b'" -W "*.pch -k 'b'" -W
"*.obj -k 'b'" -W "*.pdb -k 'b'" -W "*.idb -k 'b'" -W "*.inc -k 'b'" -W
"*.inl -k 'b'" -W "*.ppm -k 'b'" -W "*.LIB -k 'b'" -W "*.pbxproj -k 'b'" -W
"*.pbxuser -k 'b'" -W "*.doc -k 'b'" -W "*.ogg -k 'b'" -W "*.lib -k 'b'" -W
"*.plg -k 'b'" -W "*.opt -k 'b'" -W "*.rmf -k 'b'" -W "*.rmx -k 'b'" -W
"*.ogg -k 'b'" -W "*.ncb -k 'b'" -m "Initial AncientArena import"
AncientArena FluffyRabbits AA_Dev

Then I check out the module to my local machine again,
try to compile and get like 26 linking errors...
I don't have the source here, but blenderXX.obj and I think interiorXX.obj were involved...
now if I go ahead and overwrite all the files in my CVS folder with the original ones (before the zip/upload/cvs thing), it compiles... but then I get an error if I exit the game (in platformMemory.cc, line 464, static void treeRemove(FreeHeader *hdr) ->
if(prev)
prev->nextQueue = next;

Anyone ANY idea what might be going on here????? I've really tried everything... (zipped it after compiling, zipped it "clean", included the *obj files into CVS, removed them, etc.... now I'm really stuck...)
Thanks a lot!!!

EDIT: oh yeah, and I've used a similar import command for another repository on the same server, which is working great...
