Comment (by kencu):

 The last bazel I built easily on 10.6.8 was 0.9.0, so I did this in my
 SnowLeopardPorts repo of pegged ports:
 {{{
 # peg bazel at 0.9.0 for older systems
 if { ${os.platform} eq "darwin" && ${os.major} < 11 } {
     github.setup              bazelbuild bazel 0.9.0
     checksums                 rmd160
 5cb89e5598a2c27c8ce6c30bad9107f67d7547ee \
                               sha256
 efb28fed4ffcfaee653e0657f6500fc4cbac61e32104f4208da385676e76312a
 }
 }}}
 I haven't looked at it recently to see if I can get some newer system to
 build it. You're right, bazel is a total bear to sort out.
