[R-SIG-Mac] unprecedented errors at start-up

[Massimo Pinto]

Greetings all

I have left R aside for about a week and upon going back to it I have
found errors which I had not encountered before. I have upgraded to
OSX 10.6 recently and these errors may be a consequence of such
upgrade.

A first error encountered at start-up refers to the use of my locale:

========

During startup - Warning messages:
1: Setting LC_CTYPE failed, using "C"
2: Setting LC_COLLATE failed, using "C"
3: Setting LC_TIME failed, using "C"
4: Setting LC_MESSAGES failed, using "C"
[R.app GUI 1.31 (5537) i386-apple-darwin9.8.0]

WARNING: You're using a non-UTF8 locale, therefore only ASCII
characters will work.
Please read R for Mac OS X FAQ (see Help) section 9 and adjust your
system preferences accordingly.

============

when trying to install a binary package from BioConductor, using the R
GUI, I get:

similarly, when trying a source package:

============================

This situation won't change if I set the locale to

> Sys.setlocale("LC_ALL", "en_GB.UTF-8")

Has anyone experienced this before?
Thank you in advance
Massimo
