Re: Latest git sources fail to compile w/gnutls on debian stable

[Paul Eggert]

To be honest I'm not sure I would mess with this stuff if you're not an expert. 
I.e., if you want to run more-bleeding-edge software, by far the easiest way to 
do that is to upgrade to a more-bleeding-edge version of Debian.

That being said, the Debian package list doesn't list any "libgnutls-dev" 
package for jessie, which is the current Debian stable. That is, 
https://packages.debian.org/jessie/libgnutls-dev reports an error. If you are 
getting libgnutls-dev from some source other than Debian, that might explain the 
problem - but then, this would not match your desire to run a stable version, so 
I am puzzled as to what your system's state is. You might want to audit 
/etc/apt/sources.list before proceeding.

jessie's libgnutls-openssl27 is indeed 3.3.8-6+deb8u4 currently; at least, 
that's what https://packages.debian.org/jessie/libgnutls-openssl27 says. 
2.12.20-8+deb7u5 is for wheezy, which is the obsolete stable release. Perhaps 
you installed some wheezy packages atop a jessie system a while ago? or are 
trying to do the reverse? I'm not sure I'd recommend that....
