Do you have anything installed in /usr/local or /sw? If so, rename  
those directories, clean and try again. Software installed in /usr/ 
local or /sw can interfere with MacPorts (because, as you see,  
software likes to look there for things, though we don't want it to).

sudo mv /sw /sw-off
sudo mv /usr/local /usr/local-off
sudo port clean --work someport

where "someport" is whatever port failed. Then try again.

"port contents boost" shows all files that got installed by boost.  
This is then piped through grep to show only those files whose names  
contain "regex-mt". On my systems (10.4.11 Intel and PowerPC) I see:

$ port contents boost | grep regex-mt
   /opt/local/lib/libboost_regex-mt-1_35.dylib
   /opt/local/lib/libboost_regex-mt.dylib
$

You don't see that, so your boost is not installing those files...  
not sure why...

You could do this:

sudo port deactivate boost
sudo port clean --work boost
sudo port configure boost
open $(port dir boost)

Then go into the work directory, into the boost source directory, and  
attach the config.log file to an email reply. I'll run the same on my  
system and see if I see any differences that might point to the problem.

Then to clean up, don't forget to:

sudo port clean --work boost
sudo port activate boost

You mentioned you were on Mac OS X 10.4.11... are you on Intel or  
PowerPC? Do you have at least Xcode 2.4.1? If not, download and  
install Xcode 2.5 from:

FYI, an enhancement request has already been filed to update boost to  
1.36; if you want to test it you can grab the portfile from here:
