libsdl: invalid command name "vercmp"

[rigstars2@…]

I keep getting this error -

Error: Unable to open port: invalid command name "vercmp"

when I try to install ffmpeg (sudo port install ffmpeg) or if I try to upgrade this libsdl (sudo port upgrade libsdl)

I have updated to latest ports doing (sudo port selfupdate) followed by a (sudo port upgrade outdated) and even ran (sudo port sync)

OS I'm using is Mac OS X Lion and installed using trunk base when Lion was still very new .. Any help, please.

Thanks!

Please run "port version" to see what version of MacPorts you really have. The "rpm-vercomp" command, which has been in MacPorts for years and years, was renamed to "vercmp" a couple versions of MacPorts ago. Please also attach the main.log file of the failure; I've looked in the ffmpeg port and it doesn't itself call vercmp so I need to see the log to know what's really going on.

port version returned Version: 2.0.99

also, the full error message I get is this

#sudo port install ffmpeg

here's a snippet of the main.log

Ah, it's the libsdl port that has the problem.

P.S: Remember to use WikiFormatting.

Still, I don't see why it would be a problem.

I still believe your MacPorts is older than the vercmp command, meaning it's pretty old. You mentioned having run selfupdate, but selfupdate won't upgrade you at all until MacPorts 2.1.0 final is released. Please install MacPorts 2.1.0 beta 1 instead.

thanks ryan. Appreciate the help. I uninstalled the version I had and download and installed 2.1.0 beta 1 but after installing it, the version still said MacPorts 2.0.99 anyways, I'm no longer getting those errors now. So, I think I'm good. Thanks again.

[ryandesign (Ryan Carsten Schmidt)]

Correct, MacPorts 2.1.0 beta 1 identifies itself as 2.0.99. MacPorts 2.1.0 final will identify itself as 2.1.0.
