no gcc 4.1after rebuild

[arnuld]

as advised on this mailing list. i added this line in "/etc/mk.conf":

WANT_GCC41=yes

i also noted that "/usr/lib" has 2 directories: gcc34 and gcc41 and on
my newly installed 1.8.1 release, "gcc --version" gave "gcc 3.4". so i
fetched the sources using cvsup using my 1.8-release supfile. then i
did this:
# cd /usr/src
# make buildworld
# make buildkernel
# make installkernel
# make installworld
# make upgrade
# reboot
this took 6 hours in total. and after reboot, i see "gcc --version"
gave "gcc 3.4"  :-(
what the heck ?   why i am not getting "gcc 4.1" based system ?

(BTW, one thing that surprised me is during this whole system rebuild,
i did NOT get any error. seems strange to a Linux based user like me)
