Binary packages not rebuilding against updated libraries

[Artur Szostak]

Hi,

I have a Portfile for a library (called CPL) that was linked against Cfitsio from a week ago. Cfitsio was updated very recently. What I expect is that during the installation of CPL, MacPorts is able to figure out that Cfitsio changed and that CPL needs to be rebuilt. However, during the "Scanning binaries for linking errors" stage it indicates "No broken files found". Why would the MacPorts mechanism not be working?

The relevant parts from "otool -L /opt/local/lib/libcfitsio.dylib":
        /opt/local/lib/libcfitsio.dylib (compatibility version 6.0.0, current version 6.3.44)
and from "otool -L /opt/local/lib/libcplcore.dylib":
        /opt/local/lib/libcplcore.26.dylib (compatibility version 28.0.0, current version 28.0.0)
        /opt/local/lib/libcfitsio.dylib (compatibility version 5.0.0, current version 5.3.41)

Surely MacPorts should see that what libcplcore.dylib was linked against is no longer compatible with the installed libcfitsio.dylib? or am I not understanding how compatibility version is working on MacOS?

Kind regards.
