UPD 02.03.2012 obsolete replacement:

Package libreadline5-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  libreadline-gplv2-dev lib64readline-gplv2-dev
