FracSim_0.2.zip
http://cran.stat.ucla.edu/bin/windows/contrib/2.3/

RDCOMClient_0.91-0.zip
http://www.omegahat.org/R/bin/windows/contrib/R-2.3.0/

segmented_0.1-4.zip
http://cran.r-project.org/bin/windows/contrib/2.1/

VGAM_0.6-9.zip
http://www.stat.auckland.ac.nz/~yee/bin/windows/contrib/2.3/

These are the versions I found and the locations. Other than perhaps segmented all seem to be positioned as compatible with v2.3.x, but I own that I could be incorrect in my assessment of the situation.
