Could not find module ‘SG’ and ‘PGF2’ while building

@krangelov Do you know why this is happening?. I was able to create the .so file but runghc glosses.hs command resulted in this error.

:~/GFT/GF-master/src/ui/android# runghc glosses.hs 

glosses.hs:1:8:
    Could not find module ‘SG’
    Use -v to see a list of the files searched for.

glosses.hs:2:8:
    Could not find module ‘PGF2’
    Use -v to see a list of the files searched for.
