Ah, out of curiosity I download the latest mysql-5.0 universal build and 
there all of the library files in lib *are* indeed universal (which can 
be verified by a doing a "file lib*"):

~/Downloads/mysql-5.0.67-osx10.4-universal/lib$ ls -l
total 265624
-rw-r--r--@ 1 nad  staff      4380 Aug  5 06:14 libdbug.a
-rw-r--r--@ 1 nad  staff      2929 Aug  4 05:30 libmysql.imp
-rwxr-xr-x@ 1 nad  staff  15367288 Aug  5 06:15 
libmysqlclient.15.0.0.dylib
-rwxr-xr-x@ 1 nad  staff  15367288 Aug  5 06:15 libmysqlclient.15.dylib
-rw-r--r--@ 1 nad  staff  17629984 Aug  5 06:15 libmysqlclient.a
-rwxr-xr-x@ 1 nad  staff  15367288 Aug  5 06:15 libmysqlclient.dylib
-rwxr-xr-x@ 1 nad  staff  15437700 Aug  5 06:15 
libmysqlclient_r.15.0.0.dylib
-rwxr-xr-x@ 1 nad  staff  15437700 Aug  5 06:15 libmysqlclient_r.15.dylib
-rw-r--r--@ 1 nad  staff  17716472 Aug  5 06:15 libmysqlclient_r.a
-rwxr-xr-x@ 1 nad  staff  15437700 Aug  5 06:15 libmysqlclient_r.dylib
-rw-r--r--@ 1 nad  staff   5389152 Aug  5 06:15 libmystrings.a
-rw-r--r--@ 1 nad  staff   2258096 Aug  5 06:15 libmysys.a
-rw-r--r--@ 1 nad  staff    562976 Aug  5 06:14 libz.a

$ diff libmysqlclient_r.15.0.0.dylib libmysqlclient_r.15.dylib
$

So, it looks like the 5.1 universal download is slightly broken and the 
copying suggestion should work.
