Do you mean "install time" or "build time"?

We do all *sorts* of checks for the presence, and capabilities, of various libraries in the autotools and CMake build processes, so checking at build time and only compiling the security stuff into the dissector if we have a version of libcrypt that can support it would not be doing something we haven't already done in the past, so that wouldn't be a version to reject that change.
