[R-SIG-Finance] PerformanceAnalytics - Error in UseMethod("time<-")

[Heiko Mayer]

Thank you all for the feedback. I was able to replicate the error and I know when it occurs, but have no clue why.
I have installed the latest R version (2.9.1) and libraries PerformanceAnalytics and zoo. Under that environment, "charts.PerformanceSummary" worked. 
However, after installing Rmetrics packages according to "https://wiki.rmetrics.org/install_rmetrics"
   source("http://www.rmetrics.org/Rmetrics.R")
   install.Rmetrics()
it doesn't work anymore when you load library "fPortfolio" (in addition to PerformanceAnalytics and zoo).
Does anyone experienced problems with fPortfolio before?

Below please find the sessionInfo:
