One More Try -- HELP

["Miller, Matt" <Matt.Miller@expanets.com>]

Am I sending this question to the right list?

After attempting to install the libreadline4 and libreadline4-dev packages
(which failed), I now repeatedly receive the following error message:
/bin/bash: error while loading shared libraries: /bin/bash: undefined
symbol: history_max_entries
This problem disables my ability to enter any other init level other than
single-user mode. For example: init 3 results in:
/bin/bash: error while loading shared libraries: /bin/bash: undefined
symbol: history_max_entries
As it is I had to run init=/bin/tcsh at lilo in order to even get into
single-user mode. I am unable to boot into bash or sh. I could only find
this one reference:

Any ideas?
