They also mention stx-exparser. That is used, but apparently only by workflow, not by releaseManager. And its README explains that it depends on the Spirit miniboost package! But only at build time. RM itself doesn't need it. On rhel6 all the boost files needed can be found under /usr/include/boost. That's not currrently the case for rhel7.
Possible short-cut
It may be that we can get by with the rhel6 binaries of RM programs and externals to begin with. (The rhel5 build of GoGui, another Qt-based program, is perfectly usable on rhel6 and comes up with no complaints on rhel7.) Ultimately we should have a native rhel7 build, but if the rhel6 binaries are usable the db updates and Jenkins interface could be tested much more quickly.
