I have the RMB option here (also Gentoo), but selecting it gives me this:

Sorry

Your system is not currently supported (/proc/<pid>/smaps was not found)

... where <pid> is the process-ID of the process in question.  (It still 
shows a bit of the UI but no memory stats, of course.)

Indeed, the smap files in /proc/* aren't there.  However, that's because 
I don't have the kernel option that turns them on 
(CONFIG_PROC_PAGE_MONITOR, in the kernel config under filesystems, pseudo 
filesystems, /proc file system support, enable /proc page monitoring) 
enabled.

Of course gentoo lets the end user (aka gentoo system sysadmin) choose 
their own kernel and set their own config.  For those running a distro 
that ships pre-configured/pre-built kernels, it's possible they've turned 
that off for security or other reasons.  If so, they may have patched 
their kde to not offer that option since it wouldn't work anyway on the 
kernel they ship.

A perhaps more likely possibility is that the kpart that provides that 
functionality is a part of a different kde package, and you don't happen 
to have the necessary package installed.
