How to find which ports depends on a given one when using macports? I want to find which ports depends on a given installed port (texlive in my case). I found port deps texlive, but this is working in the "wrong" direction. How can I do it?
Use port dependents &lt;portname&gt;. From man port:


  dependents
         Lists the installed ports that depend on the port portname.


There is no way to search for all ports (including those not installed) depending on a certain port.
