At the end of ESXi host update, the FreeBSD virtual machines complained about the VMWare tools being "unsupported".
First, uninstall the current VMWare tools:
# cd /usr/local/bin
# perl vmware-uninstall-tools.pl

That's because the provided script is looking for perl under /usr/bin. As of FreeBSD 10.1, perl is no longer a system binary and after the install, the binary is under /usr/local/bin.
So, edit the following files and replace /usr/bin/perl with /usr/local/bin/perl in the following three files.
