[R] RMySQL install

I am having trouble installing RMySQL on a clean install of Fedora Core 4 64 bit on a dual dual core machine (that is, two dual core processors). Seems like the LD_LIBRARY_PATH is incorrect, but I don't seem to have it quite right yet.

There are a few mentions of this problem in google, but thus far none of the "fixes" and fixed my problem. I've tried defining the LD_LIBRARY_PATH environment variable, and setting the PKG_CPPFLAGS, and PKG_LIBS environment variables as well. No luck so far.

(initially would not compile, but specification of the PKG_CPPFLAGS, and PKG_LIBS got the compile to complete without errors). I still cannot load the library. My error message is:

> library(RMySQL)

Loading required package: DBI
Error in dyn.load(x, as.logical(local), as.logical(now)) :

        unable to load shared library
  /usr/lib64/R/library/RMySQL/libs/RMySQL.so: undefined symbol: mysql_field_count
Error in library(RMySQL) : .First.lib failed for 'RMySQL'

Trying to install the newest RMySQL on the newest R.

I find libmysqlclient.so in the following location(s).

[root@BX mtaylor]# locate libmysqlclient.so



I set the LD_LIBRARY_PATH according to these results, then double checked that it was set. (I also set it to /usr/lib64/mysql3/mysql as another iteration)

[root@BX mtaylor]# printenv LD_LIBRARY_PATH /usr/lib64/mysql3/

Just to be sure...

[root@BX mtaylor]# printenv PKG_CPPFLAGS -I/usr/include/mysql

[root@BX mtaylor]# printenv PKG_LIBS

(also tried PKG_LIBS=-L/usr/lib64/mysql3/mysql and PKG_LIBS=-L/usr/lib/mysql)

I recompiled the package each time with R CMD INSTALL RMySQL_0.5-7.tar.gz, but I always get the same error message.

appears to install ....

just to make sure the headers are actually in the specified location...

[root@BX mtaylor]# ls /usr/include/mysql

There is a dial in here somewhere that I think I am turning the wrong direction - just can't see it. Any experience with this one?
