I am using postgresql 8.2 and ruby 1.8.5. While I compiled plruby 0.5.0 on cygwin, the last step failed, some symbols in libpostgres.a were missing. And I do not know how to compile it with visual studio.... And on AIX 5.1, the compiling works, but failed on `make test`, pgmaster terminated on signal 4. Could somebody help me? Thanks.
