apache2-2.2.11 Configure failure - build error

[pete.gadomski.public@…]

apache2 is not building on my PPC iBook with MacOS X 10.4.11 (Tiger). Excerpts:

$ sudo port install apache2
--->  Fetching apache2
--->  Attempting to fetch httpd-2.2.11.tar.bz2 from http://www.ibiblio.org/pub/mirrors/apache/httpd
--->  Verifying checksum(s) for apache2

Error: Target org.macports.build returned: shell command " cd "/usr/local/var/macports/build/_usr_local_var_macports_sources_rsync.macports.org_release_ports_www_apache2/work/httpd-2.2.11" && make all " returned error 2
Command output: 

Lots of output, then:

Error: Status 1 encountered during processing.

I have cleaned (sudo port clean --all apache2) before attempting install again, with no success.

/usr/local is not a supported prefix for MacPorts, see the the FAQ.
