Subramanian,

quantstrat (and blotter, and FinancialInstrument) work fine on older
versions of R (at least back to 2.9.2)

R-forge, on the other hand, only builds binary packages on the newest
version of R.  If you want to avoid the 2.14 warning (which should be
harmless), you'll need to use the .tar.gz version of the packages, and
compile them yourself.  Under most *nix systems, including linux and
Mac, this is easy.  Under Windows, you'll need to install and configure
Rtools.

As for the 'Defaults' package, which is the actual *Error* above, it is
available on CRAN, and should be easily installed with 

install.packages('Defaults')

Having just yesterday installed R and all these packages including xts
(from CRAN, as the R-Forge version isn't stable right now) and quantmod
(from R-Forge, as with blotter/FinancialInstrument/quantstrat/TTR) on
clean Windows machines, I am pretty certain that everything is fine on
the CRAN/R-Forge side.

Regards,
