the library name for Clutter always used API version in the soname and
in the pkg-config file, to allow parallel installability.

the problem is that we defined the API version as "$major.$minor",
allowing parallel installability between development cycles and stable
cycles. it was actually a mistake we continued for a while, and I
strongly discourage anyone maintaining a library to follow that
particular scheme: development cycles should always have the pkg-config
and the soname of the next stable cycle, to allow an easier upgrade path
for application developers.

ciao,
