With rpm that's have been built with this in mind you can rebuild the binary rpm from the source rpm using the construction rpm -ba --with .... xxx.spec Of course this requires you build from source so you can't use anything like yum to automatically update your packages unless yum knows where to find the prebuilt packages with the required options. OpenPKG rpm (www.openpkg.org) (which works independently of the system rpm [if it exists]) allows you to do what you want. That is because openpkg normally provides source rpms and also the rpm -qi output indicates the options that the rpm was built with and the build environment (openpkg-tools) makes use of this information. It's a very nice facility but has the disadvantage that it can not be used by the system rpm. It does however work on most Linuxes and also other platforms such as Solaris and FreeBSD. If you only want to do this for one rpm then it is probably too much overhead but if you want to extend this to multiple servers and packages it may be worth looking to see if OpenPKG solves your problem.
