A question about Mac OS X installation

Hi there,

I am having problems installing Io on OS X (10.5.3), and would dearly
love some help.

Specifically, if I download the src from the website (or git it from
the repository) then the:
"make vm"
and:
"make install"
seem to work, except when I try to run:
"io"
----
it gives me the following error:
dyld: Library not loaded: @executable_path/libiovmall.dylib
  Referenced from: /usr/local/bin/io
  Reason: image not found
Trace/BPT trap
----
however, I can io_static.  This problem seems to be quite pervasive
as well, since it seems that the addons also suffer from a similar
problem (being unable to load required dynamic libraries) and so I am
left with the vm, but no addons.

If, on the other hand I install using macports:
"port install io"
then it seems to install fine, and running:
"osxvm"
seems to work, however I don't seem to have control over the
installation of addons.

Any suggestions as to how to proceed would be greatly appreciated!

On a side note, when I run the interpreter interactively, it has only
basic text entry capabilities. Am I correct in assuming that readline
and editline capabilities are part of the addons that I am unable to
install?

Thanks for any/all help!

Ta,
Andrew
