Hi,
In order to test the gui by manually changing to 32-bit python, I typed
the following command:
export VERSIONER_PYTHON_PREFER_32_BIT=yes
Python was then working in 32-bit mode, which allowed the import of wx
within python, hence allowing the dependency check for wx to pass and
the launch of the gui.
However, I then got the following error:
====
ImportError:
dlopen(/Library/Python/2.6/site-packages/scipy-0.10.0.dev_20110325-py2.6-macosx-10.6-universal.egg/scipy/special/_cephes.so,

Testing further, it turns out that the relax prompt yields the same
error, similarly to the relax test-suite (i.e. the following commands
all yield the same error: "relax", "relax -g", "relax -u", "relax -s",
"relax -t", "relax -h", etc).
My scipy version is 0.10.0.dev (running under python 6.2.1, now in
32-bit mode). As reported in a recent post at
https://mail.gna.org/public/relax-devel/2011-04/msg00050.html
(Message-id: <4DB419A4.1030201@xxxxxxxxx>), testing scipy yielded some
errors and failures which could be related to the current problem (or not).
Any idea what this could be a problem with running 32-bit python under
Mac OS X, or a problem specific to relax ???
Anyway, it turns out that simply switching from 64-bit to 32-bit python
under Mac OS X does not allow the use of the gui...
Thanks a lot !!!!!!

Hi,
I just installed wxPython on my Mac running OS X in order to be able to
run the relax gui.
I installed "wxPython2.8-osx-unicode-py2.6" from
"http://www.wxpython.org/download.php#stable";.
When trying to start the gui, I get the following message:
""RelaxError: To use the GUI, the wx python module must be installed."
When I try to import wx withon python, the module seems there, but not
working, as I get the following error:
====
import wx

no appropriate 64-bit architecture (see "man python" for running in
32-bit mode)
====
On the wx python website, it is said that "These binaries should work on
all versions of OSX from 10.3.9 onwards on either PPC or i386
architectures. Since they use the Carbon API they are limited to running
in 32-bit mode."
However, my machine, a Macbook pro, is 64 bit and python runs in 64 bits
by default. I found that python can be set to use 32 or 64 bits.
However, I am afraid that these settings are system-wide. Would there be
a way that relax tells the system to run python in 32 bit mode, maybe
only when the gui is invoked ?
Maybe this is too much asked... However, if it is simple, I guess it
would simplify the life of many users with recent Mac computers...
Thanks a lot !
