[Discuss-gnuradio] Re: GNU Radio - Skipped components

[Josh Blum]

To be honest, the version requirement is somewhat arbitrary. I looked 
through the lxml changelogs and picked something recent that I thought 
would come on most operating systems.

Ubuntu 8.10 is ok, but 8.04 which is about 1.5 years old is not ok... I 
suggest 2 options:

1) Edit config/grc_grc.m4 and change the line with the version 
requirement to match your install. The configure should pass and you can 
install and try out grc. If it works just fine, let me know so I can 
lower the version requirement.

2) Download the lxml source tarball for version 2.xxx or whatever is 
newest. Try to install it and see if the configure passes and grc works.

Thanks!
