perl makefile.pl出错啦！！！！！！！

[supergirl_sunny]

perl makefile.pl时，出现了以下错误信息：
unable to find a perl 5(by these names: d:\program files\perl\bin\perl.exe perl.exe perl5.exe perl 5.8.8.exe miniperl.exe, in these dirs: .D:\program files\perl\bin.......)Writing Makefile for WordNet::QueryData

怎么解决？？？？？
请各位指教！！！！！

你的perl解释器装在哪里?

[supergirl_sunny]

装在d:\program files\perl里

[supergirl_sunny]

我编译其它pl文件的时候都是正常的

这是MakeFile.pl的内容

use ExtUtils::MakeMaker;

# It is bad that the default WordNet directories are in two places,
# here and at the beginning of QueryData.pm ($wnHomeUnix and
# $wnHomePC). These need to be synchronized. I need to import those
# variables from QueryData.pm.

die "*** Please set the WNHOME environment variable to the location of your\n*** WordNet installation. QueryData.pm will not work otherwise.\n*** Alternatively, you can make the installation in the default\n*** location, C:\\Program Files\\WordNet\\2.0 on Windows, or /usr/local/WordNet-2.0 on unix.\n" unless exists $ENV{WNHOME} or -d "C:\\Program Files\\WordNet\\2.0" or -d "/usr/local/WordNet-2.0";

WriteMakefile(
'dist' => { 'COMPRESS' => 'gzip', 'SUFFIX' => '.gz', },
'NAME' => 'WordNet::QueryData',
'VERSION_FROM' => 'QueryData.pm',
);
