Two things with this. First, the checking and rejecting of bad Boost versions is new since we just started to understand the issue. So older versions do not have this protection. Second, GNU Radio doesn't /prefer/ a version of Boost; it'll likely just picks the first one it finds that is valid. With 3.4.2, the only non-valid Boost versions would be those before the minimum version of 1.35. Most likely, it'll take whichever the sym link to libboost_xxx.so it finds. For instance, my machine has: /usr/lib/libboost_filesystem-mt.so -> libboost_filesystem.so.1.48.0 It'll depend on how to installed, order of install, or OS issues that would determine this if you have multiple versions installed. You can always tell cmake (and configure before it) which Boost libraries and include directories you want to specify. With cmake, you use -DBoost_LIBRARY_DIRS=..., -DBoost_INCLUDE_DIR=..., and even library-specific directives (if multiple Boost libs are installed into the same directory) like -DBoost_FILESYSTEM_LIBRARY=.../libboost_filesystem-mt.so. I don't recall how to set these using configure, though.
