Can not install CProtect package

[Yanjun HU]

hi, I am green-hand of g-ctan user. My computer OS is : gentoo+kde4.7+texlive2011+g-ctan2011.1 .
texlive was installed by using "emerge texlive" command.

Yesterday, I found that I need the cprotect package used in my beamer. So I am puzzled that I can not install this package. The "g-ctan -l | grep cprotect" command result shows cprotect is not exist.

However, in the "texlive.tlpdb" ("/var/cache/g-ctan/texlive.tlpdb"), there are :
name cprotect
category Package
revision 21209
...

use the command (referend from create_package_list() function ):
grep -C 1 "^category Package" texlive.tlpdb | awk '{print $2}' | sed -e "s/Package//" -e '/^[ ]*$/d' > package.names
will create the file named package.names which size is 67.8KB
meanwile, use "g-ctan -u" will create the file named package.names which size is 9.8KB

I read the "common" ("/usr/share/g-ctan/ common" ),there are:
# TeXLive has been released from this revision in its repository (but
# add 1 to make checks easier, everything before is not newer than the
# things shipped with the release.
G_RELEASE_REVISION=23181

I guess the function create_ebuild() named in the g-ctan should not call "check_version"?
