Not an expert. But it looks like if ntl is not present at configuration time zn_poly has a fall back. See include/support.h NTL use is very limited, 2 operations. If NTL is found profile/ntl-profile.c is used which calls the following ntl headers: #include <NTL/lzz_pX.h> #include <NTL/ZZ_pX.h>
If not profile/ntl-profile-dummy.c will be used. In short as it is, nothing will break if ntl is built afterwards, but if it is built before then dependencies of zn_poly should have -lntl added. This scenario is possible when upgrading and in parallel building atm. The sage library and extensions are safe as everything is linked against ntl by default.
