I have tried to install php 5 and firefox 3.6 from ports. Both attempts failed with similar (as far as I see) condition. The error from installing php follows. What is wrong? Code:===> php5-5.3.4 depends on file: /usr/local/bin/autoconf-2.68 - not found ===> Verifying install for /usr/local/bin/autoconf-2.68 in /usr/ports/devel/a utoconf ===> Building for autoconf-2.68 gmake all-recursive gmake: Entering directory `/usr/ports/devel/autoconf/work/autoconf-2.68' Making all in bin gmake: Entering directory `/usr/ports/devel/autoconf/work/autoconf-2.68/bin' autom4te_perllibdir='..'/lib AUTOM4TE_CFG='../lib/autom4te.cfg' ../bin/a utom4te -B '..'/lib -B '..'/lib --language M4sh --cache '' --melt ./auto conf.as -o autoconf.in autoconf.as:1: /usr/local/bin/gm4: Warning: Excess arguments to built-in `_m4_po pdef' ignored autom4te: /usr/local/bin/gm4 failed with exit status: 1 gmake: *** [autoconf.in] Error 1 gmake: Leaving directory `/usr/ports/devel/autoconf/work/autoconf-2.68/bin' gmake: *** [all-recursive] Error 1 gmake: Leaving directory `/usr/ports/devel/autoconf/work/autoconf-2.68' gmake: *** [all] Error 2 *** Error code 1 Stop in /usr/ports/devel/autoconf. *** Error code 1 Stop in /usr/ports/lang/php5. *** Error code 1 Stop in /usr/ports/lang/php5.
