readline doesn't fetch

[Charles Darwin]

I don't know what I'm doing here but I changed this line
master_sites    gnu ftp://ftp.cwru.edu/pub/bash/
in  this file
/opt/local/var/macports/sources/rsync.macports.org/release/ports/devel/ 
readline/Portfile
to this
master_sites    gnu ftp://ftp.gnu.org/gnu/readline/

and now it's installing.
