Can't compile bdb 0.6.5 on Mac OS X Snow Leopard (10.6.1)

I’m trying to use Ruby-WordNet on my recently-Snow-Leopard-upgraded Mac,
and I’m getting an error saying that it can’t find the bdb library:

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in
gem_original_require': no such file to load -- bdb (LoadError) from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:inrequire’
/Library/Ruby/Gems/1.8/gems/wordnet-0.0.5/lib/wordnet/lexicon.rb:34
[snip]

Predictably, line 34 of lexicon.rb says:
34 require ‘bdb’

I used porticus to install the macports package for rb-bdb, and it says
I have 0.6.5_0 installed:

$ port -v activate [email protected]_0
Port command started with PID 93833
Activating rb-bdb @0.6.5_0
Error: port activate failed: Image error: rb-bdb @0.6.5_0 is already
active.

I can see a bdb.bundle file installed:
cto@bigmac-2 (722) $ ls -l
opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin10/bdb.bundle
-rwxr-xr-x 2 root admin 218168 Oct 18 22:08
opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin10/bdb.bundle

…but I can’t find a bdb.rb ruby library anywhere that would satisfy
the require.

Just for kicks, I tried to download the bdb source after installing the
port, and running ruby extconf.rb. It errors with “extconf.rb:90: libdb
not found (RuntimeError)” Then “make” gives me this:

cto@bigmac-2 (727) (master) $ make
make[1]: *** No rule to make target ruby.h', needed bybdb.o’. Stop.

So no luck with the macport and no luck with compiling. Does anyone have
experience with this problem? Any help or suggestions would be greatly
appreciated!

Many thanks!

/opt/local/lib/ruby/* directories are not in Ruby’s library path by
default. You’ll have to add those directories to your RUBYLIB
environment variable.

Stop.

After upgrading to SnowLeopard you need to reinstall the Developer
Tools to get ruby.h and friends.
