Cannot Update Circular Dependency problem

Hi everyone,
I wanted to update a few packages but ran into dependency cycle problem.I did pacman -Syu and then tried to update but all in vain.I searched the forum and found some solutions but I am still unable to solve the problem.This is the error message that I get:

 extra is up to date
 community is up to date
:: The following packages should be upgraded first :
    pacman
:: Do you want to cancel the current operation
:: and upgrade these packages now? [Y/n] y

resolving dependencies...
warning: dependency cycle detected:
warning: udev will be installed before its util-linux dependency
looking for inter-conflicts...
:: gnupg and gnupg2 are in conflict. Remove gnupg2? [y/N] y
:: kmod and module-init-tools are in conflict. Remove module-init-tools? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: gcc: requires gcc-libs=4.6.2-5

I am not sure about the real approach to this problem.I cannot update pacman neither can I delete all the packages to resolve dependencies.
Any help will be appreciated Thanks.

Re: Cannot Update Circular Dependency problem

This is really handled in quite alot of threads on the forums already. Simply running:

# pacman -S pacman

should fix it for you.

Additional info about the kmod/module-init-tools warning.

Better to say 'no' to the syncfirst prompt and just let everything be updated at once.

You should always do a full upgrade. Partial upgrades are not supported, you can't just "update a few packages" w/o running the risk of breaking things.
