I made compat-gnutls34 and compat-nettle32 packages , because half of
Centos 7 depends system gnutls and you can't just upgrade it .
After install compat-gnutls34 and compat-nettle32 before run
./configure you just need run export PKG_CONFIG_PATH=/usr/lib64/compat-
gnutls34/pkgconfig:/usr/lib64/compat-nettle32/pkgconfig

Just a note you just need gnutls-3.4.7 if you will use MIT Kerberos
integration if you use Heimdal Kerberos I think gnutls of Centos 7still enough [3] .
