Hello David
Update just in case someone else is trying the same thing:
I tried to install it using EPEL, but after 'installing' EPEL, 'sudo yum install openconnect' fails with the following error:
--> Finished Dependency Resolution
Error: Package: openconnect-7.07-2.el6.x86_64 (epel)
Requires: libpcsclite.so.1()(64bit)
And this seems to have to do with the fact that they removed the pcsc-lite package from Amazon Linux as it "was not relevant to AWS"
(cfr. https://forums.aws.amazon.com/thread.jspa?messageID=772449). So there seems to be an open feature request to bring it back, but I don't think they did that already, hence the error. (Also, I read somewhere that Amazon Linux has drifted quite far away from what it was orinigally based on, that many people are experiencing trouble installing EPEL stuff on Amazon Linux.)
But I managed to finish compiling it locally. Unlike what was mentioned on the website, I also needed to do
sudo yum install libxml2-devel
And after that, I could successfully run
./configure --with-vpnc-script=/etc/vpnc/vpnc-script --disable-nls
make
make install
The next step will be trying to set up a connection...
Thanks for the help.

Packages do exist. Try EPEL. But if you want to build against libraries
you need to install e.g. libxml-devel. Or 'pkgconfig(limxml-2.0)' etc.
