This is about testing 6.10.0.20081007.

1. DoCon works with it.

2. The question is how to `install' Backspace and UpArrow in ghci.

I make it from source by 6.10-candidate and also by itself -- on Debian Linux. And ghci does not process Backspace and UpArrow. ./configure reported configure:2303: checking whether ghc has editline package configure:2314: result: no

And the Debian system area shows the files /usr/lib/libedit.so.2 /usr/lib/iceape/components/libeditor.so /usr/lib/libedit.so.2.9

The editline package requires the header files, not just the .so libraries. You can get those by installing the editline-dev package. (After which you'll need to rebuild ghc.)

Correction: you probably want the Debian libedit-dev package. -Judah
