I'm so sorry . I found that command "patch" is not in my system. - -! this time , i install the "patch 2.6 ". but, when i use "make patch " the terminal show this:

root@guo-qijiang-desktop:/tmp/perl-5.10.1/Cross# make patch
cd .. ; if [ ! -e ./CROSS_PATCHED ] ; then \
        patch -p1 < Cross/Makefile.SH.patch; \
        patch -p1 < Cross/installperl.patch ; mv installperl installpe
+rl-patched; \
        sed -e 's/XXSTRIPXX/arm-linux/' installperl-patched > installp
+erl; \
        touch CROSS_PATCHED ; fi
