One of the packages you tried to install asked for this, in this list:

Looking into your post:

it is py25-hashlib that is the culprit.

I was able to install it. Then I got a later Python:

The procedure followed was (do a 'sudo -s' so save writing:

First uninstall python25 and dependencies:
# port uninstall python25
--->  Unable to uninstall python25 2.5.2_5+darwin_8, the following  
ports depend on it:
--->  	py25-gobject
--->  	py25-numeric
--->  	gstreamer

# port uninstall gstreamer at 0.10.19_0
--->  Deactivating gstreamer @0.10.19_0

# port uninstall py25-numeric
--->  Deactivating py25-numeric @24.2_1+macosx
--->  Uninstalling py25-numeric @24.2_1+macosx

# sudo port uninstall python25

Then I noticed there was an unregistered python - those seems to  
confuse MacPorts. OS move it:
# cd /opt/local/bin/
# mv python python1

Then I installed python_select and python25:

To fully complete your installation and make python 2.5 the default,  
please run

	sudo port install python_select
	sudo python_select python25

--->  Cleaning python25

After that follow the instructions:

# sudo port install python_select
Skipping org.macports.activate (python_select +darwin_9) since this  
port is already active
--->  Cleaning python_select

# sudo python_select python25
Selecting version "python25" for python

And finally to py25-hashlib:

# port install py25-hashlib
Portfile changed since last build; discarding previous state.

share/man/man3/bn_print.3.gz already exists and does not belong to a  
registered port.  Unable to activate port openssl.
Error: The following dependencies failed to build: openssl
Error: Status 1 encountered during processing.

So here I just remove the unregistered file:
# rm /opt/local/share/man/man3/bn_print.3.gz
# port activate openssl @0.9.8j_0
--->  Activating openssl @0.9.8j_0

So now it worked. Try py25-hashlib again:
# port install py25-hashlib
--->  Fetching py25-hashlib
--->  Verifying checksum(s) for py25-hashlib
--->  Extracting py25-hashlib
--->  Configuring py25-hashlib

--->  Staging py25-hashlib into destroot
--->  Installing py25-hashlib @2.5.4_0
--->  Activating py25-hashlib @2.5.4_0
--->  Cleaning py25-hashlib

So now I git t installed. - I got beyond the point where you got stuck.
