[R] install RMySQL under Mac OS X 10.4.7

[Luo Weijun]

Hello All,

I tried to install RMySQL package, but the error
messages says there is no such package, even though I
did see RMySQL is there in the contributed package
list in all mirror sites of CRAN I tried. Not sure
what is the problem.

> mysql.home <- '/usr/local/mysql' 
>
Sys.putenv('PKG_CPPFLAGS'=paste('-I',file.path(mysql.home,'include'),sep=''))

>
Sys.putenv('PKG_LIBS'=paste('-L',file.path(mysql.home,'lib'),'
-lmysqlclient',sep='')) 
> install.packages('RMySQL', repos =
"http://www.biometrics.mtu.edu/CRAN/",dependencies =T)
dependency ''RMySQL'' is not available
> install.packages('RMySQL', repos =
"http://www.biometrics.mtu.edu/CRAN/")                
Warning in download.packages(pkgs, destdir = tmpd,
available = available,  : 
         no package 'RMySQL' at the repositories

I tried download the package manually under unix, and
install it from within R, and no luck too. 

cd ~/download/R
curl -O
http://www.biometrics.mtu.edu/CRAN/src/contrib/RMySQL_0.5-7.tar.gz

> install.packages( 'RMySQL_0.5-7.tar.gz', repos =
NULL)
Error in gzfile(file, "r") : unable to open connection
In addition: Warning message:

attached base packages:

"utils"     "datasets"

could anybody tell me what happens here, and how to
fix the problem? Thank you so much!
