I am not needing parrot (just checking its state) but compilation failed. Don't know if it is expected or not. In any case, this might be useful:
../data/locales/ja.txt:15: parse error. Stopped parsing with U_INVALID_FORMAT_ERROR
couldn't parse the file ja.txt. Error:U_INVALID_FORMAT_ERROR
make[1]: *** [../data/out/build/icudt26l_ja.res] Error 3
make[1]: Leaving directory `/home/ambs/Junk/Parrot/parrot/icu/source/data'
make: *** [blib/lib/libicuuc.a] Error 2
