[Gimp-docs] automake version problem

[gbstack]

after I used git to download gimp-help-2 clone,I ran this command:
/./autogen.sh --without-gimp ALL_LINGUAS="en zh_CN"/

but I got this error message:
/Looking for latest automake version ...
  You must have automake 1.10 or newer installed to compile gimp-help-2.
  Download the appropriate package for your distribution,
  or get the source tarball at ftp://ftp.gnu.org/pub/gnu/automake/
Please install/upgrade the missing tools and call me again.

/however, my automake version is 1.7.9...

anyone can tell me what I should do?
