I think we have reasons to translate that to 'parsec>=2.1' or
'parsec<2.2' (I would personally use even parsec=188.8.131.52)
* we won't upgrade to parsec 2.2 unless that is included in some
* we can expect Parsec 2.2 to be mostly API-compatible with 2.1 if it
comes to existence (but the author of the package didn't want to make
