"can not find sources" error

Hi, I'm using php-4.1.1 on Redhat 7.2. I want to install mailparse. There was a problem when I install the mailparse-0.9.2.tgz. What is your suggestion? [root@www mailparse-0.9.2]# pear install /home/umuta/mailparse-0.9.2.tgz 8 source files, building running: phpize aclocal: macro `AC_ADD_LIBPATH' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_LIBRARY_WITH_PATH' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_LIBRARY' defined in acinclude.m4 but never used aclocal: macro `AC_ADD_INCLUDE' defined in acinclude.m4 but never used You should update your `aclocal.m4' by running aclocal. building in /var/tmp/pear-build-root/mailparse-0.9.2 running: /tmp/tmp2YypIe/mailparse-0.9.2/configure configure: error: can not find sources in /tmp/tmp2YypIe/mailparse-0.9.2 or .. `/tmp/tmp2YypIe/mailparse-0.9.2/configure' failed 1[root@www mailparse-0.9.2]# Thanks...
