% otool -L
        /opt/local/lib/libxslt.1.dylib (compatibility version 3.0.0,
        current version 3.28.0)
        /opt/local/lib/libexslt.0.dylib (compatibility version 9.0.0,
        current version 9.17.0)
        /opt/local/lib/libxml2.2.dylib (compatibility version 12.0.0,
        current version 12.1.0)
        /opt/local/lib/libz.1.dylib (compatibility version 1.0.0,
        current version 1.2.8)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
        version 1213.0.0)

I also did, roughly:
(sudo find /opt/local -name "*.dylib or *.so" -print0 | xargs -0 otool
-L) | grep libxml2
and also included the library name when the linkage was found. I then
parsed that output & all of it looks clean.  This clearly does not
include executables, .apps, or other linked binaries.

I will admit that I did not yet parse -all- of the files in the crash
log yet to verify their linkage. I just did the most obvious suspects
plus the hammer method above. - MLD
