BUG: expat upgrade breaks subversion

Description

After upgrading expat, I get:

$ svn dyld: Library not loaded: /opt/local/lib/libexpat.0.dylib

Referenced from: /opt/local/bin/svn Reason: image not found

It seems that svn should be rebuilt (by increasing the revision).

Resolution: fixed
Status: newclosed

Upgrading expat again should fix this; the port now installs a symlink for the older name of the library (since things using expat shouldn't need a rebuild for this version upgrade).

If the expat library used a different name (/opt/local/lib/libexpat.1.dylib instead of /opt/local/lib/libexpat.0.dylib), then this often means that the new version is not ABI-compatible (otherwise, why changing the name?). Are you sure that this was OK?

(current,age,revision) is for each library: /opt/local/var/db/dports/software/expat/1.95.8_1/opt/local/lib/libexpat.la

5 5 0

/opt/local/var/db/dports/software/expat/2.0.0_0/opt/local/lib/libexpat.la

6 5 0

This means that 1.95.8_1 supports interfaces 0 to 5, and 2.2.0_0 supports interfaces 1 to 6, and that a program that uses features of interface 0 will break if linked to 2.2.0_0! So, IMHO, the symlink to the older revision should not have been added since the new revision had dropped interface 0.
