The day was 25/11/12 21:15 when , Storm Dragon had this to say......:
Hi,
I have searched for this and not found anything, but it seems like it should be
possible. Is there a way to package a currently installed program? I have a
friend who is having trouble with a new Arch install getting Orca working. I
know for sure my version of Orca is working, so I wanted to package it for him,
send it to him, and let him instal with pacman. I'm just not sure how to do it.
Of course, if my version of Orca works on his install that means there is a bug
somewhere, but he needs it to be working in order to access information to file
a bug lol, kind of a catch 22.
Thanks
Storm
I found this a while ago, I haven't tried it for a while though so I'm
not sure if it still works with the newer Pacman
