There is an error in PKGBUILD.
Instead of: $srcdir/$_pkgname-$pkgver-$subversion
it should be: $srcdir/$pkgname-$pkgver-$subversion

It's not an error, is necessary cause name of package is different from name of software (plugins  plug-ins)
Here http://aur.pastebin.com/FNG8ae9g is updated version of the package 2.2.0-2

Answer 1

I have finally solved my problem... Here is what I did to do so. I must confess that it is someone in a french mac forum that told me how... And I understood better since it was in French.
My problem was related to the fact that my installer did work right. That I knew. In fact, it didn't open niether .dmg nor .pkg files.
I downloaded the pacifist from the net. I took my 'installation and reparation" disk of mac os x and put it in the machine. Be carefull : don't activate the installation program, because you will reformat you hard disc and loose everything (that was what I was really scared of...).
When the disc shows on you desk top, open the pacifist and, with it, go and seek ONLY the component you thing you need to remplace on your hard disc. For me, as I said, it was the installer. So I reinstall the installer, and I could therefore install mpeg2 and finally finish my portfolio.
Hope it can be helpfull for other, as they where for me. Thanks.
