I think you did the right thing. We'll debug further if the Cabal update doesn't work for you.

ok + thanks. I guess I'll wait for updated cabal if it is imminent .
Re (1) I could double-check this in the meantime perhaps, but what to look for exactly? 
(I relied on "cabal install wx cabal-macosx" on an empty local user pkg lib to get it right.)

There are a couple of possibilities:

1) (which I think can be discounted, given your description of 'removed everything and started again') is that you didn't do a clean build. The dependency checking for wxc is rather fragile (bacause Cabal does not know about C dependencies).
2) More likely: the latest version of wxcore on Github is 0.90.0.3 - this was bumped when I messed up some dependencies in one of the releases (I didn't notice because *I* hadn't cleaned up properly before testing. Have you tried pulling from the tip of the master branch on Github in the past few days (I commited the updates to Github on June 10th - haven't updated cabal yet as I have been too busy - will try to do so this evening (UK time).

In other words, I think this may be my fault, for which my sincere apologies.

Best regards

Hello - is this a fault with wxc (or associates) ? 

due to "Undefined symbols".

This is based on an i86_64-only wxWidgets 2.9.3 build on mac os 10.6.8 snow leopard with xcode 3.2.6 and with ghc 7.0.4  (HP 2011.4.0.0 64).

I discovered some legacy mess in the local pkg installations so removed everything from --user pkgs and rebuilt it all again 
cleanly with cabal install, with no apparent errors at this stage. The install looks fine now but I still get the same error and am now stuck..
