http://fedoraproject.org/wiki/Packaging/Guidelines#Compiler_flags bind-dyndb-ldap 0.1.0-0.15.b is built without $RPM_OPT_FLAGS; 0.14.b did not have this problem. Possible (untested) fix: -export CFLAGS="`isc-config.sh --cflags dns`" +export CFLAGS="`isc-config.sh --cflags dns` $RPM_OPT_FLAGS"
Good catch, thank you for report.
Fixed in bind-dyndb-ldap-0.1.0-0.16.b.fc15.
