 Hello ,

 i do use Firefox ESR (45 - 52 ) as browser and use quite some extensions.
 For Youtube i do use "Watch with MPV" , and on OSX , i had a working mpv
 version 0.26 that enabled the firefox extension to access properly the mpv
 client.

 However, lately, whenever i tried to install mpv with macports (on Lion,
 or Mavericks, or other OSX) it would not function anymore.

 As i could not localize the error, i resorted to copying the working
 /opt/local/ directory from the functioning partition over to the other
 partition, where i would like enable the same functionality.

 This works well when i go "upstream" , eg. from Lion upwards (at least
 tried with Mavericks);

 i do have several SL partition where i would like to "implement" this
 feature aswell,
 however when i copy over the /opt/local/   and /Macports (Programs)
 directory , afterwards, upon evoking "mpv" command, i get the following
 error

 {{{
 dyld: Library not loaded:
 /System/Library/Frameworks/CoreMedia.framework/Versions/A/CoreMedia
   Referenced from: /opt/local/lib/libavcodec.58.dylib
   Reason: image not found
 Trace/BPT trap
 }}}

 i do understand that this CoreMedia.framework is not present in the
 Frameworks on Snow Leopard. Can i just copy it over from the Lion
 partition (which i would rather avoid) or is there another way to please
 this libavcodec.58.dylib?


 Thank you very much.

Comment:

 MacPorts is designed so that the ports you install work on the OS version
 on which you installed them. Often they will continue working on later OS
 versions, possibly without all the functionality they would have if they
 were built on the newer OS. It is completely unsupportable to take
 software compiled for one OS version and try to run it on an earlier OS
 version. If you move from one OS version to another, you should reinstall
 all ports; see wiki:Migration.

 You are correct that the instructions in wiki:howto/InstallingOlderPort
 only pertain to a single port. You could of course follow the same
 instructions for any number of ports, but MacPorts is not really designed
 for you to be able to install older versions of ports. If you want to
 backdate your entire MacPorts installation to an earlier point in time,
 you could of course do that by uninstalling all ports, checking out an
 older commit of the macports-ports repository, running `portindex` in it,
 and then installing the ports you want.

 The issue tracker is for bug reports and feature requests, not technical
 support; for that, please ask on the macports-users mailing list.
