You've shown us that "_sqlite3.so" links with "libsqlite3.0.dylib",  
and that "libsqlite3.0.dylib" does not exist in /opt/local/lib. This  
means that "_sqlite3.so" probably won't be able to make use of the  
functionality provided by "libsqlite3.0.dylib".

To answer the question in the subject line, "deactivate" deactivates  
a port, by removing the hard links from their locations in /opt/ 
local. For example, the hard link /opt/local/lib/libsqlite3.0.dylib  
was removed. Now libsqlite3.0.dylib only exists in /opt/local/var/ 
macports/software/sqlite3/3.5.6_0/opt/local/lib, so that you can  
easily reactivate the port again if you want. If you do not want,  
then you can uninstall the port, which will actually remove the files  
from the disk.
