I see that querypairwise1 tests for the running time of a test case.
Could there be a glitch with high loads on the Travis build machine
causing inconsistent runtime performance? The error message for clang
reads:

    Running test: querypairwise1... FAILED
    Test with 50 repetitions took 0.003521 secs
    Test with 500 repetitions took 0.055811 secs

Whereas the same test succeeded for the g++ build. I'll retry to build
tomorrow.

Thanks, I'll see how autoconf checks for libuuid and zlib. Use of
icuconfig is indeed discouraged by the ICU maintainers . If I can't get
the PR build properly without pkgconfig, I'll make both libicu and
pkg-config optional. To do so, I'll try to get Travis build with 14.04
LTS, which might require a few build runs.

I'll notify you when the CJK pull request passes Travis.

Cheers,
Robert
