I've checked the sources and looked for the adler32 and BZ2_decompress functions that were listed in the log. Both of these files are from the Plan 9 source tree so I believe these warnings should be considered false positives and ignored. The adler32 function in particular is a completely different implementation. Actually, I'm surprised there aren't many many more of these warnings, since plan9port contains all it's own C libraries and such.
I'm closing this since I believe this is the expected behavior for the plan9port ebuild.
