gnome2 problem

hi everybody,

I have some problems when I want to emerge gnome2 with the library libgtop
When I want to compile it, the response is :

../../include/glibtop/global.h:94:24: libgettext.h: No such file or directory
make[3]: *** [open.lo] Error 1
make[3]: *** Waiting for unfinished jobs....

!!! ERROR: The ebuild did not complete successfully.
!!! Function gnome2_src_compile, Line -5519, Exitcode 2
!!! compile failure

What can I do so as to  finish the compilation of gnome2

thanks
