After a recent ports update (MacPorts 1.4.0 from the repo a few days ago), I noticed an interesting quirk.<br><br>The current port for py-psycopg (version 1.1.21) requires libraries from python 2.4 (port python24) and PostgreSQL 
8.2.3 (port postgresql82):<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">$ port deps py-psycopg<br>py-psycopg has library dependencies on:
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <span style="font-weight: bold;">postgresql82</span><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; py-mx<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <span style="font-weight: bold;">python24</span><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; openssl<br></blockquote><br>Yet, if you want to install postgres82 with the python 
<span style="font-weight: bold;">variant</span>, the Portfile for postgresql82 wants Python 2.5:<br><br><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote">

Is it ok for python24 and python25 to co-exist and both be active at the same time? I presume that if I install python24 in sequence before python25, then after installing python25 I can then install postgresql82 with the python variant and then go ahead and install py-psycopg to let it build against its desired libraries from both python24 and postgresql82? Hopefully this won&#39;t lead to problems because I want to later install the trac port with the postgres 
<span style="font-weight: bold;">variant</span>  and trac can be set up to use py-psycopg<br><br>Has anyone tried this out yet?<br><br>Best regards,<br><br>T.M.<br><br><br><br>
