Thanks Ian,
I now do have both jhs and jgtk running. The fix did not require as
extensive an overhaul as you suggested, but your advice seems sound.
My MacBook Pro is not a "clean" machine: Over years when I got a new
Mac I'd just copy all the old code over. I've also installed stuff with
both "Fink" and "MacPorts", which are not really compatible. Bad habits.
I know that this machine has several versions of Python, for example.
After the emails from Bil Lam, I did "echo $PATH" and found that the
leading directories in my search path were "/scisoft/...". SciSoft is
a package of astronomical image processing software, and contains lots
of gtk files. Since I'm not using the scisoft stuff right now, I removed
the startup files that put these directories in the search path. And
that seems to have done the trick. I have no clue as to why that fixed
the problem with jhs!
Just as a test, I just installed j701 on my wifes MacBook. That
machine has little non-standard software. That installation went quite
smoothly.
You were surely on the right track concerning old gtk files as the
culprit. One message from all this is that while j701 may be "stable",
depening on your Mac, your installation may run into serious problems.
Maybe there should be a warning to anyone who is new to J to just use
j602 -- at least on a Mac.

Last Wednesday I wiped my j701 beta installation on my Mac as
thoroughly as I could, and reinstalled the stable j701. It was
painless (which wasn't the story of the beta). AFAICT both JHS and
JGTK are working ok.
So let me volunteer some help here. I hope it will be "help" and not
just add to the confusion, because I'm not at all an expert in either
linux nor the Mac OS 10.6 flavour of it. (I'm running an intel iMac
with snow leopard = Mac OS 10.6.6, the latest release I think.)
Playing around with j701 beta had taught me a lot more about
Mac-out-of-linux than I ever wanted to know, and given me
treasure-troves of gtk binaries all over the place. I thought I'd have
a spring-clean and install the stable j701 release.
Patrick says that JHS is not working either, which surprises me:
there's something deeply wrong here because it's always been
trouble-free for me.
A Spotlight search of my Mac shows me I don't have a file called
libc.dylib anywhere, though it is mentioned inside 3 text files:
core.ijs, jfile.ijs and socket.ijs. I suspect it's a red-herring.
It'd be good if we could start a wiki page with a few war-stories,
which might turn into a FAQ specifically for Mac OS X -- a minority of
J users but not a negligible one I deem. Maybe we'll even get a
step-by-step troubleshooting guide.
@Patrick, if I were you and not feeling inquisitive, I'd uninstall
j701 and j701-beta as thoroughly as I could.
This means search-and-destroy all gtk folders and dylibs wherever they
may be found, including inside /Library/Frameworks .
If you mess around with gtk these things proliferate like rabbits --
and they're mostly dodgy builds from way-back.
Make a note of everything you delete and rely on Time Machine to get it back.
Don't forget to drag the old J7 icons out of Dock too.
Folder /j701-user seems safe enough to leave alone, however, so you
don't have to lose your user-work.
And gtk dylibs packaged inside other apps like Glade seem safe enough
too, and won't be found by accident.
And you can safely leave folders /j602 and /j602-user alone.
Leave Terminal severely alone while doing this and try to do
everything by using Spotlight and Finder.
The Mac has a lot of "epigenetics" on top of linux, which it uses to
locate and manage files.
If you move/delete files using Terminal and don't watch out for
associated hidden files, the gremlins come out to play.
Empty Trash and restart the Mac.
Then re-install from j701a_mac_intel.dmg by dragging the folder /j701
into /Applications, and get JHS working.
If the red J doesn't work, it doesn't bode well for the green J.
Once the red J (aka JHS) is working, use it to install all addons.
This should build a healthy /Applications/j701/gtk --which on my Mac
is 22 MB (21,473,162 bytes for 236 items).
If the green J still doesn't work, pm me and we'll try and find what's
different on your machine and mine.

I guess it should, J assume mac can find this file without given the full
path name, if this is no the case, a number of other references to this
files inside J base library and addons would need fix.
I do not use mac so unsure how mac actually find it shared library.

OK, it is there in /usr/lib; a link to a link:

[uni:~] jph% ls -al /usr/lib/libc.dylib

What does that tell us? Should /usr/lib be in my search path?
