Many packages require a lot of memory these days to compile, gcc being one of them. With only 768 MiB of RAM you will *definitely* need a swap file/partition. In addition, with so little memory you won't be able to compile packages in tmpfs. Thrashing of your disks will go off scale as the machine will try to swap memory to disk and back again. For these reasons what Joost suggests is the best way. You could try to share /usr/portage via NFS, but since this is a remote server I am not sure the security model will be adequate for most use cases. It would be easier to copy your VPS filesystem over to your local machine which is not resouce constrained, chroot into it and then sync portage and emerge everything you need with --buildpckg. Then copy over the binary packages to the VPS and emerge them there with --usepkg or --usepkgonly. If you are disk space constrained on the server, you don't have to copy over the binary packages manually each time. Instead you can set up your home PC as a binary host and serve the binary packages over ssh or over http/s to the VPS client. Essentially, you will be creating your own bespoke binary distribution on your home PC, then downloading it and installing it at your VPS.
