R help - Oct 2003 - DBI Interface broken

Hi, I'm trying to use R's DBI interface but it appears to be broken. I
am using R 1.8.0 on Linux, and have just installed DBI 0.1-6 through the command
'install.packages("DBI")'.
	Installation went fine, but now when I try to do a simple dbConnect(), it
won't do anything besides complaining about an internal error:

	> library(DBI)
	> dbConnect(anything)
	Error in dbConnect(anything) : couldn't find function
".valueClassTest"

	> dbConnect
	standardGeneric for "dbConnect" defined from package "DBI"
	  defined with value class: "DBIConnection"

	function (drv, ...) 
	.valueClassTest(standardGeneric("dbConnect"),
"DBIConnection",
	    "dbConnect")
	<environment: 0x91201a8>
	Methods may be defined for arguments: drv 

	Anyone has a clue on what might be going on? Is it DBI working for any of you
using R 1.8.0?

	Thank you,

Why do you post twice, to R-help and to R-bugs? In order not to
cross-post I repeat my answer on your bug-report:

Package "methods" has a namespace from which .valueClassTest() is not
exported, but it's in there, try:
  methods:::.valueClassTest

I think .valueClassTest() is not intended to be called by the user, so
the bug seems to be in package DBI rather than in R, and the maintainer
of DBI (David A. James <dj at bell-labs.com>, in CC) will certainly fix
it.
