Yes: ca 10 secs on my machine. Why do you call it a `problem', though?
system.time(library(lme4))

Profiling this shows that almost all the time is spent on setting up S4
methods:
$by.total
total.time total.pct self.time self.pct
"eval" 10.32 100.0 0.02 0.2
"library" 10.32 100.0 0.00 0.0
"system.time" 10.32 100.0 0.00 0.0
"<Anonymous>" 9.92 96.1 0.00 0.0
"insertMethod" 8.62 83.5 1.86 18.0
"getAllMethods" 8.36 81.0 0.00 0.0
"mergeMethods" 7.94 76.9 0.00 0.0
I am sure the packages' authors are aware of that.
