gcc7 seems to have installed correctly. You can confirm by doing

fink list gcc7

And seeing if they have 'i' in front of the entries.

Regarding ghc-text:

Its PostInstScript (/sw/var/lib/dpkg/info/ghc-text.postinst) runs the 
script "/sw/share/doc/ghc-text/register.sh".
And its PreRmScript (/sw/var/lib/dpkg/info/ghc-text.prerm) runs the 
script "/sw/share/doc/ghc-text/unregister.sh --force"

But you're getting the error that 'register.sh' and 'unregister.sh' do 
not exist.

Are register.sh and unregister.sh present in the output of this command 
(one line)?

dpkg-deb -c /sw/var/cache/apt/archives/ghc-text_1.2.1.3-2_darwin-x86_64.deb

In my case, I see both scripts contained within the deb at the very end 
of the output.

Also, what is the output from 'dpkg -s ghc-text | grep Status:' ?
