Re: [gentoo-alt] emerge-webrsync in prefix?

[Rabbe Fogelholm]

Some weeks have passed since this issue came up; wish I'd be reading the list more
frequently. For whatever it's worth I remember having trouble with subversion behind
a corporate firewall when bootstrapping prefix Gentoo on Solaris half a year ago. I
used to run a script that was supposed to go unattended for many hours, and I was
using the code below as a workaround for the subversion issue.

When reading the code snippet you should assume that PROXYHOST is set to a hostname
or IP address, and PROXYPORT is a port number. And `die' is a function that makes the
script print a message and die of course.

Note that the first lap hangs for a couple of minutes (?) before failing, so some
patience is required when trying it out.

# Configure proxy for subversion, if it seems
# to be needed. Run this code twice: the first lap
# creates the config directory and files and fails
# because we have not done the proxy configuration;
# on the second lap we configure for proxy and should
# succeed. If we are not behind a proxy we should
# succeed on the first attempt.
