[OS X TeX] Re: [MacTeX] Bug in Preference Pane

[Alessandro Andretta]

I sent an e-mail to the list about these issues on the 23rd (see below)
but it must have gone astray during the short interruption over the last couple of days.
It seems now that Te XLIve utility works fine. One more question: should there be
a TeXLIve-2011-64 directory at all? When I choose it I get an error message.

Regards,

I have used the pre-test version of TeXLive 2011 for several weeks, and it worked fine. Two days ago I upgraded to Lion and
today I downloaded the official MacTeX, rather than updating via the TeXLive Utility.
After installing MacTex I fired the  TeXLive Utility that told me that critical updates where needed. After this it mentioned that 
three updates were available, I clicked update all, and after a while TeXLive Utility got stuck into 

2011-07-23 09:05:53 +0000 Error tlu_ipctask[13429]	running fmtutil-sys --byfmt cont-en ...

The second problem I have is that choosing the 64 binaries in the system preference pane yields a 
disconcerting answer from TeXShop, saying that there is no TeX!
Looking into the directories, it seems that the 64-bits part date back to May 31st…

Any clues?
