I believe that CLK_TCK is replaced with CLOCKS_PER_SEC and no longer supported
in glibc-2.4

Created an attachment (id=82292) [edit]
libggi-2.1.1-CLK_TCK.patch

fixes problem.

See this http://bugs.gentoo.org/show_bug.cgi?id=126400
I've made new GGI 2.2 stuff with patches.
So, your problem can be resolved. ;)

Applied a different less intrusive patch, that defines CLK_TCK if it's not.
