How to comletely remove some package(i.e. no cfgpro, no !mtime)?

Generally speaking, something like:

1) emerge -Cp package
2) emerge -pv --deep --update --newuse world
3) emerge -pv --depclean
4) revdep-rebuild -p

This should get rid of a package and any dependencies that are no longer needed.

NOTE: There have been some discussions about needing to do one or more
of these steps multiple times. Hopefully my answer will spur someone
with knowledge of that to point out if and when that is required.

Cheers,
Mark

At build time, some packages will link against unwanted libraries.  Even though the unwanted library may not be strictly required, the ebuild may not support a way to disable it with use flags.  For this reason, it's a good idea to add another step to your sequence:

1.5) emerge -av depclean

Some libraries that seem to actually link against the installed version at build time.  This results in broken dynamic links when the installed version is replaced with the freshly built one.  In these situations, a simple workaround is to unmerge the installed version before rebuilding it.

Ah, thanks. so the idea is:

1) emerge -Cp package
1.5) emerge -av depclean
2) emerge -av --deep --update --newuse world
3) emerge -pv --depclean
4) revdep-rebuild -p

With step 1.5 to remove these old libraries? Seems to me that doing
this sort of depends on having done the whole process sometime before
cleanly through step 4. Fine with me though. Thanks for the
explanation.

Cheers,
Mark

Well, after you do step 1) it's best to purge any unneeded dependancies before proceding any further.  Extra libraries pollute the build environment.

I believe that you can specify an empty CONFIG_PROTECT on the command line in order to disable it:

CONFIG_PROTECT="" emerge --unmerge foo

The mtime check currently cannot be overrided without hacking portage.py.

if (pkgfiles[obj][0] not in ("dir","fif","dev","sym")) and (lmtime != pkgfiles[obj][1]):
	print "--- !mtime", pkgfiles[obj][0], obj
	continue
