dylib wowes after OS upgrade

[Brian Dunn]

just upgraded osx from 10.4 to 10.5, and I'm getting lots of dylib  
problems.

for example:
$ /opt/local/bin/ssh
dyld: Library not loaded: /opt/local/lib/libkafs.0.dylib
   Referenced from: /opt/local/bin/ssh
   Reason: image not found
Trace/BPT trap

and:

$port install subversion
:
:
grep: /opt/local/lib/libgssapi.la: No such file or directory
sed: /opt/local/lib/libgssapi.la: No such file or directory
libtool: link: `/opt/local/lib/libgssapi.la' is not a valid libtool  
archive

I think that second one is due to problems with linking to the new  
system kerberos. anyone know how to fix this mess? any one had success  
doing an OS upgrade and fixing their ports dylibs?
am i sol and just have to do a clean install?
