我正试图在常春藤桥计算机上安装mesa 10到linux debian wheezy。为此，我需要更新libdrm。
我按照这些说明操作： http://www.linuxfromscratch.org/blfs/view/svn/x/libdrm.html
我已经成功构建了软件包，但checkinstall失败并出现以下错误：
(Reading database ... 201946 files and directories currently installed.)
Unpacking libdrm (from .../libdrm_2.4.60-1_amd64.deb) ...
dpkg: error processing /home/dapper/Downloads/libdrm/libdrm-2.4.60/libdrm_2.4.60-1_amd64.deb (--install):
trying to overwrite '/usr/include/xf86drmMode.h', which is also in package libdrm-dev 2.4.40-1~deb7u2
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:
/home/dapper/Downloads/libdrm/libdrm-2.4.60/libdrm_2.4.60-1_amd64.deb
/var/tmp/tmp.PmSU0v8QiA/dpkginstall.log
我对linux并不陌生，但我不确定如何解决这个问题。
