#55550: Current ntop broken (and fails to rebuild) by current rrdtool
--------------------+------------------

--------------------+------------------
 Port rev-upgrade is reporting ntop as broken and failing to rebuild it,
 because ntop references a lib that's no longer present in the current
 `rrdtool`.

 {{{
 $ port installed rrdtool
 The following ports are currently installed:
   rrdtool @1.5.5_1
   rrdtool @1.7.0_0 (active)
 }}}

 Indeed the current `rrdtool` doesn't contain that lib:

 {{{
 $ port contents rrdtool | grep _th
 }}}

 ... outputs nothing.

 Now if I activate the older version:

 {{{
 $ sudo port activate rrdtool @1.5.5_1
 --->  Computing dependencies for rrdtool
 --->  Deactivating rrdtool @1.7.0_0
 --->  Cleaning rrdtool
 --->  Activating rrdtool @1.5.5_1
 --->  Cleaning rrdtool
 }}}

 then I do have that lib:

 {{{
 $ port contents rrdtool | grep _th
   /opt/local/lib/librrd_th.4.dylib
   /opt/local/lib/librrd_th.a
   /opt/local/lib/librrd_th.dylib
 }}}

 and the rev-upgrade no longer finds ntop broken:

 {{{
 sudo port -v rev-upgrade
 --->  Scanning binaries for linking errors
 --->  No broken files found.
 }}}

 So current MacPorts version of `ntop` is not compatible with current
 MacPorts version of `rrdtool`. Probably should explicitly depend on an
 older version, or be updated itself. (Or maybe the current rrdtool is just
 broken by not having that library; I don't know.)
