I've got some of that, too, but more in the social realm
(where it bred stiffness, frozen fear and artificiality).

Writing code, it's write-test-write-test.... Modestly
endowed monkeys plus a feedback loop. :-)

A nice thing about dynamic languages is the compile phase is
simpler, and you often have the ability to evaluate code at
runtime.

Hmmm. Which distribution are you using?

A lot of people just compile perl, install it in
/usr/local/, and let cpan install the modules.

Even if you go through your packaging system, the final
result is still a bunch of code sitting in hierarchical
directories. :-)

(My next perl installation will be in my home directory,
so that I can do absolutely all software installation, including
man pages, without root permissions.)

Well, I had to look at Traverso. It seems very cool.
I'll take my time installing it. Debian wants me to do a
heart transplant, which I'd need a backup for first. :-)

I'm looking at the downloadable installer, which will
be nice if it gives me an independent, statically compiled
executable.

Nice you could be a head bugge,... bugfinder/creator.
And for Nama, too. :-)

Yeah, that's a Net-ECI problem. We're supposed to get 256 as
a return value, or we die. :-(

To see what actually happened, try starting Nama with
the -D flag.

(I'm sure I ran into something like this before... just
don't remember the fix.)

To get quickest satisfaction, :-) try installing
Audio::Ecasound. That will be automatically used,
bypassing Net-ECI.

By the way, what kinds of signal processing would
you be wanting to do with Ecasound?

Best,

Joel
