I'm going to tinker with [werc][1] under chroot'ed Apache.
[1]: http://werc.cat-v.org/
werc requires plan9port. If I attempt to build plan9port with:
make LOCALBASE=/var/www
...
===> Extracting for plan9port-20120508p0
/bin/sh: bzip2: not found
tar: End of archive volume 1 reached
tar: Sorry, unable to determine archive format.
*** Error code 1
...
but 'make install' works as expected. I can copy
/usr/local/plan9/bin to /var/www/bin
and continue from there but I am curious why the LOCALBASE method
failed. Any speculations or comments on best practices?
