Comment (by ankitadhar):

 I am still confused. When I had installed macports, I had downloaded a
 package which did the task for me. In how to install older ports, I can am
 able to clone the repository.

 My doubts:
 1. If I clone commit of my interest in say 'Documents', and then go to
 lang/gcc-devel and run `sudo port install`, then I get the following
 error:
 `Error: Unable to execute port: Could not open file:
 /Users/ankitadhar/Documents/macports-ports/lang/gcc-devel/Portfile`.
 If this is the right way of doing then how to overcome this error.
 2. If I am required to replace all the ports in the path
 `/opt/local/var/macports/sources/rsync.macports.org/macports/release/tarballs/ports/lang`,
 then what next steps do I need to follow?

 I wish to thank you for the time and support. I am really thankful, cuz I
 am clueless without these chats.

 does not work. You need to specify which ports to install, i.e. `sudo port
 install gcc-devel libgcc-devel`. You can also check which ports are
 installed with `port installed`.
