I'll try it out (now using FreeBSD 4.9)... Hmm, now the subversion port
breaks because of a nasty dependency:
An older version of textproc/expat2 is already installed (expat-1.95.6_1)
The usual problem: 126 packages depend on expat-1.95.6_1! Thus I can't
use the subversion port at this time. This kind of dependency makes
the port system completely useless!
Note that the original problem is not with subversion, it just happened
to occur in the subversion port. The actual problem is with "dialog".
I tried making a test to show the problem with just running "dialog":
dialog --yesno question 6 50 |& tee /tmp/tt
Problem is that keys like <Tab> and <Space> are not handled. But Enter
is used. Could it be that the terminal is not set to raw mode? Without
redirecting stderr it works fine, thus I suspect a stty() is done on
stderr while the input is read from stdin. The xterm settings are also
messed up (scrolling works as if the number of lines is much less, need
to do a "soft rest" to fix that).
hundred-and-one symptoms of being an internet addict:
65. The last time you looked at the clock it was 11:30pm, and in what
seems like only a few seconds later, your sister runs past you to
catch her 7am school bus.
