make blows up with pptpd-1.4.0.tar.gz on Fedora 20

I did:
cd /usr/local/src

tar xvzf pptpd-1.4.0.tar.gz
cd pptpd-1.4.0
./configure
make

Here is the extract for when make blew up. 

.

.

I wiped all the 1.4.0 stuff and tried the same operation with 1.3.4 and make ran to completion.  Does 1.4.0 have a new prerequisite that 1.3.4 doesn't need?

Thanks
