invalid command name "..."

[Jeremy Huddleston]

So recent base has been giving me a problem...

With a fresh checkout, I do:

# First sanitize your environment to remove any reference to /opt/ 
local etc
svn co https://svn.macosforge.org/repository/macports/trunk/base
cd base
./configure && gnumake -j3 && sudo make install
…
===> making install in src/programs/daemondo
/usr/bin/install -c -o root -g admin -m 555 build/daemondo /opt/local/ 
bin
[ ! -f /opt/local/etc/macports/mp_version ] || rm -vf /opt/local/etc/ 
macports/mp_version
/usr/bin/install -c -o root -g admin -m 444 setupenv.bash  /opt/local/ 
share/macports/
/usr/bin/tclsh src/upgrade_sources_conf_default.tcl /opt/local
/usr/bin/tclsh src/dep_map_clean.tcl /Library/Tcl
invalid command name "sysctl"
     while executing
"sysctl hw.cpu64bit_capable"
     (procedure "mportinit" line 363)
     invoked from within
"mportinit"
     (file "src/dep_map_clean.tcl" line 12)
make: *** [install] Error 1


The above failure happens on my intel box when installing for i386 or  
x86_64.


The below failure happens on my Leopard G5 box:

invalid command name "get_systemconfiguration_proxies"
     while executing
"get_systemconfiguration_proxies"
     (procedure "mportinit" line 440)
     invoked from within
"mportinit"
     (file "src/dep_map_clean.tcl" line 12)
