l-m-c problems?

It seems I had to install more recent linaro image tools in order to create a 13.05 SD card. Based on previous experience this was not a complete surprise, but I had issues making linaro-media-create work on my 12.04 system. After upgrading to 13.04 I found I had issues getting the image tools to reinstall. Has anyone else run into this? Sorry for not being more specific, but it was quite a bit of flailing before I got back to something I could use.

Thanks, -dl
