I downloaded the source of 0.5.0-RC1 and tried to compile the software. Everything worked smoothly except for the ./configure script that I had patch a bit.

My /bin/sh points to dash (Debian Almquist Shell) instead of bash. As it is, the configure script doesn't work with dash because the ./configure script uses some features bash supports but dash doesn't. The necessary changes for dash are very tiny and they should not affect bash users at all.

The patch:

- Removes the function keyword from shell functions (that keyword is optional, works with bash but not with dash)

- Replaces references to Makefile.run with ./Makefile.run

I don't know how to attach patches in these feature requests so I put a simple patch on my web page:
