Well, no, this doesn't prevent pacman from installing the packages, only from
sorting them, which is usually not critical.
So pacman only prints a little warning in the --debug output when it detects
a loop while sorting the packages, but that's all.
Something like "dependency cycle detected"

I don't know if this message should always be printed, on standard pacman
output.
There could maybe be a pacman option or an external tool for detecting
dependencies cycles.
