It is not a bug. res_calendar_ews was written to use neon 0.29. It
checks the version using ne_version_match, the documentation of which
specifies that for every version of neon beginning with major version
0, all versions of neon are assumed to be incompatible:

The ne_version_match function returns non-zero if the library version
is not of major version major, or the minor version is less than
minor. For neon versions 0.x, every minor version is assumed to be
incompatible with every other minor version.

You should either downgrade to 0.29, or else have a community
developer determine if res_calendar_ews is compatible with later
versions of neon.
