No R binaries and error during 2.9.0 installation

[pawel.matykiewicz@…]

I uninstalled all previous versions of R because I though I will have quick solution but it did not help. Error looked same for upgrade though.

I goes like this:

sudo port install R
--->  Fetching R
--->  Verifying checksum(s) for R
--->  Extracting R
--->  Configuring R
--->  Building R
--->  Staging R into destroot
--->  Installing R @2.9.0_0+gcc43
--->  Activating R @2.9.0_0+gcc43
Error: Target org.macports.activate returned: Image error: /opt/local/lib/R/library/Matrix/CONTENTS already exists and does not belong to a registered port.  Unable to activate port R.
Error: Status 1 encountered during processing.

Do I really have to delete all packages to make it work?

If there is no quick resolution please advise how to install previous version of R through macports.

Thanks
