Comment (by jrd-freak@…):

 I suppose so, as this is ultimately user error. I wonder though how
 exactly I could have found out about it. Does installing `libgcc-devel`
 inform me at some point that it will deactivate `libgcc`? I do not
 remember, but I did not have to do anything to resolve the conflict, as
 far as I remember. Also, is it generally the case that such beta-ports are
 used as drop-in replacements in conflict situations or is it just
 `libgcc`? Where can I find documentation on the topic?
