I run ghc here on two machines.
And it appears now that both are under Debian Linux.
Some people here say that this RPM does not go under Debian.
Maybe, GHC can take care of Debian?
Would it help now, after `make all', `make install',
setting LD_LIBRARY_PATH or such, making symbolic links?

A typo. Module interfaces.
In any case, I could confuse things, not understanding these
only observe that the interpreted code looks 2-3 times larger.
Maybe, it is natural, maybe not, I do not know.
Another question: am I in glasgow-haskell-users.. ?
I am responding to Simon's respond to my letter to
glasgow-haskell-users.. sent a couple of hours ago,
and I had not recieved this my letter, so far.
