It is packaged as part of `abcl-contrib.jar`.

It shouldn't be obsolete, as it is packaged as part of `abcl.jar`.

This indicates that for some reason your installation cannot locate
abcl-contrib.jar.


For an ABCL installed via MacPorts, one can show the following details
of the setup that may give a bit of insight into what a "healthy"
version might look like:

--

illin:~$ which abcl
/opt/local/bin/abcl
illin:~$ cat /opt/local/bin/abcl
#!/bin/sh

# abcl.in

How did you install ABCL?  There should be two jar files, 'abcl.jar' and
'abcl-contrib.jar' which should both be located in the same directory.
At runtime, when satisfying the "(require :abcl-contrib)", ABCL
introspects the classpath on which it is launched to probe for
'abcl-contrib.jar'

Maybe you are using a custom invocation script?

A few more details on how you have installed ABCL locally and how you
are invoking it would be helpful (i.e. "I downloaded abcl-1.4.0-bin.zip;
unzipped in a directory, and I invoke it with this command").
