Hi,

I am not completely sure this is correct if we are talking in terms of 
*reprducible* builds. 

In principle an upgrade in libnghttp2 might trigger a change in the behavior of 
curl which (even if curl is only a build dependency of rust) might change the 
way rust is built. 

For this example it is merely theoretical but if you consider a build 
dependency on a compiler which on its turn depends on a lot of stuff I would 
not bet on it. 

IMHO the only way a port build might be “reproducible” is:
1. Make a clean and empty machine (from release, no ports, no packages). 
2, Check out somehow the port tree at a stable state
3. cd /usr/ports/some/port ; make

This has always been *the* way to build a “clean” port on FreeBSD. 

Unfortunately, in the last months/years, this often does not even work; and 
it’s quite sad, when it happens, to see #notabug #wontfix #usepoudriere #usepkg

All the best,

A.
