Description:
I tried to build gcolor2 this morning and the build kept failing. It is a duplicate of this Debian bug report.

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=634606

The error is:
> grep: character class syntax is [[:space:]], not [:space:]
> checking for correct ltmain.sh version... no
>
> *** Gentoo sanity check failed! ***
> *** libtool.m4 and ltmain.sh have a version mismatch! ***
> *** (libtool.m4 = 1.5.18, ltmain.sh = ) ***
>
> Please run:
>
> libtoolize --copy --force
>
> if appropriate, please contact the maintainer of this
> package (or your distribution) for help.
>
> make: *** [config.status] Error 1

Cause: Typo in configure script (noticed from this line (grep: character class syntax is [[:space:]], not [:space:])

Fix:
Add a sed statement to the PKGBUILD to fix the Bracket Expression typo.

"sed -i 's/\[:space:\]/[&]/g' configure"

Compiles fine afterwords. I didn't see a need to patch something this simple

Additional info:
* package version(s)
gcolor2 0.4-5

* config and/or log files etc.


Steps to reproduce:
Try to compile gcolor2.
