As I recall, earlier, there were needed for GHC the shared libraries
gmp  and  libreadline.so*
As I understand, I need now to install the shared library  editline  
instead of  libreadline. Is this so?

But maybe, the installation procedure 
(configure  command or  make install  command) should
search for  editline, gmp, and such,  and report an error if the GHC 
installation does not find them?
