Okay. I tried to run xconfig again, and another error came up, but it was narrowed down to a few things. I managed to fix one, which stated that the Qt3 Dev package wasn't installed, easily fixed by synaptic.

Now I just have this one error left

root@MacbookLinux:/usr/src/linux# make xconfig
  CHECK   qt
/usr/bin/moc -i scripts/kconfig/qconf.h -o scripts/kconfig/qconf.moc
  HOSTCXX scripts/kconfig/qconf.o
/bin/sh: g++: not found
make[1]: *** [scripts/kconfig/qconf.o] Error 127
make: *** [xconfig] Error 2
Is there a package named g++ that i should install? Your help is really appreciated.
