HELP!! autoconf configure problem
 

How can I instruct autoconf to build programs that reference a
directory but installs into another. eg

when I build the ncurses package....

I want the programs build by the package to access the
terminfo database from /usr/share/terminfo, so I give it the
--prefix=/usr option to 'configure'. However, I do not want
'make install' to copy the files into /usr but into another
arbitry directory. How do I specify this?
