Rebuilding all dependents when upgrading from mysql50 to mysql51 is absol=
utely
required. mysql50-client installs ${LOCALBASE}/lib/mysql/libmysqlclient.=
so.15
whereas mysql51-client installs ${LOCALBASE}/lib/mysql/libmysqlclient.so.=

-- note the changed ABI version number. Unless you use portupgrade(1)=20
or save a copy of the old shlib by other means, anything that linked agai=
nst
libmysqlclient would be rendered inoperable by the change, and must at le=
ast be
re-linked. Yes, the APIs have not changed, but APIs are a matter for pro=
grammers
at the time of writing the source code -- once compiled, it's the ABI tha=
t counts.
Cheers,
Matthew
