Ryan,

Feedback sent --  see your copy of the email set to the developer, Dan  
Smith.

Now, can someone please advise me as to what I need to do to recover  
from yesterday's failed installation, including the fix for the "py- 
serial" problem. Either that, or tell me how to undo what was done  
yesterday.

I am way over my head here, but am willing to learn to get this done,  
given guidance.

Briefly, the failed installation that started this way:
> <me>$ sudo port install py25-gtk py-serial py25-xml py25-hashlib


and ended this way:
> Error: The following dependencies failed to build: py25-cairo py25-
> numpy py25-hashlib py25-gobject libxslt
> Error: Status 1 encountered during processing.


And earlier in the log before the error occurred, it says this:
> To fully complete your installation and make python 2.5 the default,
> please run
> 	sudo port install python_select
> 	sudo python_select python25



Ignoring the reported error, I ran those two sudo commands with these  
results:
> --->  Fetching python_select

One problem is:
  I don't know what state this leaves my installation in, and I am not  
knowledgeable enough to know how to find out.  Please advise. For a  
more complete version of the installation log, see below.

Prior to where the error occurred, a repeating pattern of reports in  
the log:  "Fetching through Activating and Cleaning"  indicates that a  
lot of stuff was installed without apparent error.

The following picks up where the trouble began:
