perl脚本报错-did you run h2ph?

如题，我摘录了报错的行：
require 'syscall.ph';
        syscall( &SYS_dup2, fileno(CHILD_RD),  0 );
        syscall( &SYS_dup2, fileno(CHILD_ERR), 2 );
具体报错如下：
Can't locate asm/unistd.ph in @INC (did you run h2ph?) (@INC contains: /usr/local/lib/perl5/site_perl/5.14.2/i686-linux /usr/local/lib/perl5/site_perl/5.14.2 /usr/local/lib/perl5/5.14.2/i686-linux /usr/local/lib/perl5/5.14.2 .) at /usr/local/lib/perl5/site_perl/5.14.2/i686-linux/sys/syscall.ph line 7.
Compilation failed in require at /usr/local/lib/perl5/site_perl/5.14.2/i686-linux/syscall.ph line 5.
Compilation failed in require at ./nginx-fcgi1 line 9.
这个h2ph我真是弄不懂了。
谁来讲解一下，我应该怎么做才能不报错。
