R help - Nov 2010 - library(kernlab) --- unable to load shared library

Dear R users,
 I have recently encountered a problem with using the function `library` in
order to load the package `kernlab`.

My output of sessionInfo() is as follows:
R version 2.10.1 (2009-12-14)
x86_64-unknown-linux-gnu

locale:
[1] C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

I have installed the package by install.packages("kernlab"), and it
had
ended up
in giving a message about the package being installed successfully.

But as soon as I type library(kernlab) the output is:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared library
'/usr/local/sage/local/lib/R//library/kernlab/libs/kernlab.so':
  /usr/local/sage/local/lib/R//library/kernlab/libs/kernlab.so: undefined
symbol: dgemv_
Error: package/namespace load failed for 'kernlab'

The call to .libPaths() lists '/usr/local/sage/local/lib/R//library' and
one
more path.

I have manually checked if the package is in the directory
/usr/local/sage/local/lib/R//library
=> it is there... (at least there is a folder with the name `kernlab`)

Could you please make any suggestions concerning the causes and/or solution
of this problem ?
Any help would be greatly appreciated.

Sincerely yours,
Yuliya Matveyeva.

Yuliya -
    The error message doesn't say that the file doesn't exist --
it says that it contains a symbol which can't be resolved,
in this case dgemv_ .  A quick google search shows that this
is part of the BLAS library.  So my guess is that you have 
installed the BLAS library in some non-standard location.
You didn't mention what Linux distribution you're using, or
whether you built R and the kernlab library from source or
not, so it's hard to give specific guidance to solve your 
problem.
