Thanks Wincent, that worked.

FYI: Ragel trunk compilation steps on MacOS 10.5.2 with MacPorts installed:

# get v6.0 of ragel installed -- needed to build trunk ragel
sudo port install ragel

# also install prerequisite gperf
sudo port install gperf

# download and install prerequisite kelbt
wget http://www.cs.queensu.ca/~thurston/kelbt/kelbt-0.12.tar.gz
tar xvzf kelbt-0.12.tar.gz
cd kelbt-0.12
./configure
make
sudo make install
cd ..

# Checkout trunk ragel and install in a directory
# in home folder -- NOT in /usr/local.
# The reason is to not interfere with the ports system.
# When GCC compiles code it doesn't appear possible
# to tell it not to look in /usr/local/lib for libraries.
# So in general I've taken to putting code I compile
# from source that either:
#  1) creates libraries
#  2) creates binaries that are also made by ports
# in ~/dev/local

svn co svn://mambo.cs.queensu.ca/ragel/trunk ragel
cd ragel
./configure --prefix ~/dev/local
make
make install

# add ~/dev/local/bin to PATH before /opt/local/bin
