NOTE: this is with vmware previously installed on a 6th sensed system. It probably won't work trying to emerge then doing this, since emerge dies out anyway upon trying, unless you know how to fix the ebuild itself. If you use the tarball and installer direct from the vmware page, it will probably work fine. Also, make sure to make backups and blah blah blah.
Long story short, when I updated Sab to the newest version, it seems that vmware didn't want to run. Some say it's because of the new kernel, but I wouldn't know. Unexpectedly, vmware-config.pl died compiling the vmmon or vmnet modules. For those who have the same problem, here's a quick fix to save them the time and trouble I had (hopefully). It seems in other threads there are alternative ways to go around the problem but I might as well add my two bits to what worked.

Go grab the any-any update 113 on that page, I think it's the fourth from the bottom. Untar it. For me, the installer script refused to work, so I just did a dirty fix: removed vmblock, vmmon, and vmnet tarballs from /usr/lib/vmware/modules/source and replace them with the ones from the untarrred any-any patch. Then reran vmware-config.pl. All works well now.
Note: a couple other common problem fixes under this section below ;P
For newbies (note: no idea if this works correctly start to finish): if that's gibberish to you, then go dl the vmware tar file from the vmware site. Install it as per their instructions (probably untar it on the desktop, then console: cd ~/Desktop/name_of_vmware_folder, then sudo ./vmware-install.pl). When it comes to vmware-config.pl useage, say no you don't want to use it yet. If it doesn't give that option, which I thought it did, just go through it and let it die on the vmnet part. Then, download the above patch to the desktop. Right click, untar it. Then open up the console and (yes, I'm aware this is a long way to do it):
cd /usr/lib/vmware/modules/source
sudo rm ./vmblock.tar ./vmmon.tar ./vmnet.tar
cd ~/Desktop/vmware-any-any-update113
sudo cp ./vmblock.tar ./vmmon.tar ./vmnet.tar /usr/lib/vmware/modules/source
sudo /usr/bin/vmware-config.pl
Their installer is dumb imo, but anyway. Just answer with whatever garbage to their questions that they have in brackets after the question. You should be good to go..
If it nags about rc stuff, just sudo mkdir /etc/rc.d/rc0.d and repeat 6 times, going from rc0 to rc6 then try vmware-config.pl again.
If you have problems with vmware nagging about those files every time you reboot, one dirty way (NOTE: possibly unsafe? I don't know. I just know it works.) that works for me is to sudo kwrite /etc/conf.d/local.start and add to the very end of the file: sudo /etc/rc.d/init.d/vmware start
