Actually, never mind... Something else must be wrong. I copied the 
source tree locally and ran the build there -- the most vanilla way to 
build things.

`make check' -- as well as a single random test -- still spins...

Running under strace shows:

strace ./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb 
./runruby.rb --extout=.ext -- "./test/runner.rb" --basedir="./test" 
test/soap/test_basetype.rb
...
lots of output
...

This is on an RHEL-5.4 machine (RedHat's own older version of Ruby NOT 
installed), x86_64. The configure was run thus:

env CC=gcc44 CFLAGS="-O2 -pipe -march=nocona" ./configure 
--prefix=/usr/local/pub/ruby__1.8.7-p174 
--mandir=/usr/local/pub/ruby__1.8.7-p174/man --enable-pthread 
--disable-install-doc

The C-compiler (gcc44) is gcc version 4.4.0 20090514 (Red Hat 4.4.0-6) 
(GCC).
