解决升级gdl-python问题，不知道要不要提交bug

flies

我用的ACCEPT_KEYWORDS="~amd64"，最近emerge world的时候gdl-python升级到2.19.1-r1，依赖它的包是gdl2.24.0，编译的时候出错：
………………

google了没有类似情况，但是发现gdl-python加了gdl-python-2.19.1-gdlicons.patch这个补丁，跟出错信息好似有关联，一看补丁，写着：
#include <pygtk/pygtk.h>
#include <gdl/gdl-dock.h>
#include <gdl/libgdltypebuiltins.h>
-#include <gdl/gdl-icons.h>
#ifndef HAVE_GDL_0_7
# include <gdl/gdl-dock-bar.h>
#endif
跟出错信息的最后几行关系大了，看补丁介绍，写着：
Fix build failure with recent gdl
(Portage version: 2.2_rc15/cvs/Linux 2.6.24-gentoo-r8-mactel x86_64)
既然是用到2.19.1的补丁，我的2.19.1-r1说不定已经fix了这个bug了，决定去掉这个补丁再编译，修改gdl-python-2.19.1-r1.ebuild，把src_unpack() 中的：
# Fix build failure with recent gdl
        #epatch "${FILESDIR}/${P}-gdlicons.patch"
注释掉，然后：
ebuild gdl-python-2.19.1-r1.ebuild digest
最后emerge world通过编译。

大家觉得我需要汇报吗？这是个bug吗？

revdep-rebuild的时候又编译不过了，改回来又ok了，真是的，唉，搞不懂了…………

库版本与软件版本的兼容问题

举个小小的例子，比如有个软件的依赖是 >=libabc-1.2.3，但 libabc 现在升到了 1.5.0 ，并对 api 进行了修改，ebuild 里没有做特殊的处理的话，就会出现错误。

建议 手动 mask  出错的包，同时 keywords 最好固定，不要轻易修改，不然此类问题只会更多。
