[Lxr-general] Unable to create LXR::Lang::Generic Lang object

[nn6eumtr <nn6...@gm...>]

Can someone tell me the steps to troubleshoot the error "Unable to 
create LXR::Lang::Generic Lang object, Exuberant ctags version 5 or 
above required, found"?

I've double checked that my paths are correct for ectagsconf and 
genericconf, and the files its choking on are .c and .pl - nothing exotic.

ctags v5.8 is installed in /usr/local/bin/ctags, and /usr/local/bin is 
in my path. If I run ctags manually on the same file, it does produce a 
tags file without error.

My working directory when running genxref is the lxr root directory.

I'm using lxr 0.9.10 and the error is triggered by the first file it 
tries to index, no matter which one it encounters and what type it is.
