FreeBSD中安装PHP5.4时报如上错误，解决办法如下：
cd /usr/ports/lang/php5
make distclean make checksum
问题的原因是已存在的diskfile的checksum与该ports信息文件中的不一致，正常情况下删除/usr/ports/distfiles中的文件即可，以下是引自FreebsdBSD handbook中的例子：
Checksum Mismatch
Occasionally, a ports tarball will fail the md5 checksum test. A typical result of this would look like:
>> Checksum mismatch for tightvnc-1.2.3_unixsrc.tar.bz2. Make sure the Makefile and distinfo file (/usr/ports/net/tightvnc/distinfo) are up to date. If you are absolutely sure you want to override this check, type "make NO_CHECKSUM=yes [other args]". *** Error code 1 Stop in /usr/ports/net/tightvnc. ** Command failed: make clean build ** Fix the problem and try again. ** The following packages were not installed or upgraded (*:skipped / !:failed) ! net/tightvnc (checksum mismatch)This means that the checksum for the tarball does not match that contained in the port's distribution information file which is/usr/ports/net/tightvnc/distinfo in this case.
The first step is to delete the tarball for the port in /usr/ports/distfiles and fetch the tarball again. This will usually take care of the problem.
If the problem persists, the next step is to check the CVS Repository at http://www.freebsd.org/cgi/cvsweb.cgi/ to make sure that your ports Makefile and distinfo agree with the latest available. If not, then you need to update your ports tree.
