the error message tells you everything:
Code:
===> fusefs-kmode-0.3.9.p1.20080208_1 requires the userland sources to be installed. Set SRC_BASE if it is not in /usr/src.
you need to get the sources. i usually get them using
csup(1) using a config file from
/usr/share/examples/cvsup/ changing the tag to the desired version
Code:
...
*default release=cvs tag=RELENG_7_0 --- for 7.0 RELEASE
...
all the best,
