There is just one problem with the SRI language modeling toolkit: It doesn't come with a configure-scipt and the makefiles don't work out of the box. After an hour of searching through make output, we found out, that ubuntu does not use gawk but mawk as its standard awk implementation. Later on in the build process, this leads to weird errors.
I'll attach the changed common/Makefile.machine.i686 , so you (and I) don't have to redo the work later.
