>Description:
As can be seen on http://www.freebsd.org/cgi/cvsweb.cgi/src/release/Makefile?rev=1.951, installation of MAKEINDEXPORTS prefixes the "make all install clean" by

	echo "		env -i FTP_PASSIVE_MODE=$${FTP_PASSIVE_MODE:-no} PATH=$${PATH} \\" >> ${_MK}

which clears all environment variables, including HTTP_PROXY and FTP_PROXY which in our internal network setup here are required for the port installation to succeed.
>How-To-Repeat:
Try to use the /usr/src/release/Makefile without the port lang/perl5.8 and with NO_PREFETCH_DISTFILES being set (causing the fetching to take place at runtime)
>Fix:
Also pass through the HTTP_PROXY and FTP_PROXY variables in these two lines.
