Dear all,

I just found that some of the packages are not able to load any more, 
after I installed R2.0.1 in my Mac, it even affects my old R1.8 
installs.

It gives me errors when I load packages that contains "myEnv" settings. 
such as: RMySQL, DBI, Rggobi, etc. But others that does not require 
"myENV" is all right, like tcltk that only calls the c functions.

The errors are like:
Error in load(dataFile, myEnv) : unused argument(s) ( ...)
Error in library(DBI) : .First.lib failed for 'DBI'

I had a look at the package file that contains .First.lib,
     fullName <- paste("package", pkgname, sep=":")
     myEnv <- as.environment(match(fullName, search()))
     dataFile <- file.path(libname, pkgname, "R", "all.rda")
     rm(.First.lib, envir = myEnv)
     load(dataFile, myEnv)

I found that myEnv is not set. as the package can not be matched in 
search().
If I comment the line load(dataFile, myEnv), then the package is loaded 
without errors but there no functions is loaded at all.

It probably is something trivial. Can some one help, please?
