mono installs /usr/bin/csc.

However, /usr/bin/csc is already provided by a package older than mono, which is the Scheme compiler Chicken.

Chicken is under active development (, and is a well known Scheme compiler, among Scheme developers.

At least one package in AUR depends on both mono and chicken and can no longer be installed because of this conflict: quine-relay (

I believe /usr/bin/csc should be renamed to something else, because chicken had /usr/bin/csc first.

IMO, we should not cater to developers like the mono developers, that are oblivious to the general open source community, and wish to take over binary names in /usr/bin.

Ideally, we should have register for reserving names in /usr/bin, but this bug report is the next best thing.

Additional info:

chicken 5.0.0-1

Steps to reproduce:

Try to install both chicken and mono.
