Summary: Failed to create importing network

Initial Comment:
I am trying glame since 0.6.0 up to 0.6.2 and still get
the "failed to create importing network" error when
importing a wav (tried various one) - they all very simple.
I belive it has something to do how do you handle
plugins. Are you using glib::gmodule or own dlopen-stuff?

my system :
>uname -a 
SunOS krishna 5.6 Generic_105181-12 sun4u sparc
SUNW,Ultra-60

configure options :
'--prefix=/opt/BKgnome' '--with-gnu-ld'
'--enable-ladspa' '--disable-asm' 'CC=gcc'
--enable-ltdl-convenience

build and install went through fine.

Uh-uh, this smells like pthreads suckage. We don't have a
Solaris machine to test on, so we'll need your help to track
this down. Now the good news is, dlopening seems to work,
otherwise test-latency would have failed even earlier.
As for the pthreads issue, a test-latency run from a cglame
compiled with --enable-debug would be really enlightening.

Uhmm..., SunOS's not exactly a well-tested platform, so can
you check whether filter networks do run at all? Fire up the
command line interface 'cglame' and type '(test-latency 1)'
to run a really basic filter network. Furthermore, if you
configured glame with --enable-debug, the console output
might be pretty helpful to find out what's going on.

dlopen-screwage seems rather unlikely since importing
doesn't rely on external plugins. We're using libtool's ltdl 
for dynamic loading.

We are using libltdl for dlopen stuff. Can you try something
with the console frontend? Try

> cglame
cglame> (test-latency 10)

and watch, if it correctly counts down from 10 to 1 (ping
times on my athlon here are about 180 usecs). This checks if
basic networks do work correctly (i.e. indicate pthreads
problems).

If this works ok, try to access a dynamically loaded plugin like
cglame> (plugin-get "null")
it should print something like #<pointer 0x80de5a0> on
success and throw an exception on error.
