[Help-nano] Nano syntax hilighting Bad regex

[dave festing]

Only found one old post on here that was even close to the problem I am having, so hoping for some up more relevant information.  This post  mentioned what happens if you leave out the \< and \> and the same happens to me.  But, that is as far as I can get.

On any line, in example nanorc files that have tried, with a "\< at the beginning and a \>" at the end I get this error:

Bad regex "[[:<:]] . . . [[:>:]]": Invalid character class name

I am running nano 2.2.6, gawk 3.1.6 on linux 3.1 cross-compiled for the ARM


Appreciate any pointers.

Thanks,
