configure: error: Sorry - I need libspectrum to be available

!!! ERROR: app-emulation/fuse-0.6.0.1 failed.
!!! Function econf, Line 324, Exitcode 1
!!! econf failed


Reproducible: Always
Steps to Reproduce:
1. Emerge libspectrum if not already installed.
2. Attempt to emerge fuse


Actual Results:  
Failed ./configure step

Expected Results:  
Should proceed to build correctly.

The configure script is finding libspectrum.h ok. This error is due to
mismatched 
compiles between the libspectrum-0.1.1 and fuse-0.6.0.1 packages. The 
libspectrum-0.1.1 ebuild contains 

        econf `use_with gnome glib` || die 

so libspectrum is compiled using glib if gnome is included in USE flags. 
The end result is that the libspectrum.h header file contains: 

        #include <glib.h> 

However, the fuse-0.6.0.1 ebuild contains 

                econf \ 
                        --without-gtk --without-glib \ 
                        --without-plus3-disk \ 
                || die 

so the configure script does not run checks for glib and subsequently dies 
when it finds libspectrum.h and sees #include <glib.h>. 

There are a variety of fixes for this bug. One is to add a gnome USE flag to
the 
fuse-0.6.0.1 ebuild and use it to compile using glib. It could also be used to 
compile the gtk+ interface: 

                econf \ 
                        `use_with gnome glib gtk` \ 
                        --without-plus3-disk \ 
                || die 

The important thing is that both libspectrum and fuse are compiled with the 
same glib option. 

Oops, an embarrassing correction needs to be made. The suggested fix 
should have been: 
 
               econf \  
                        `use_with gnome glib` \ 
			`use_with gnome gtk` \  
                        --without-plus3-disk \  
                || die  
  
 
I've also noticed that the local variable "guiflag" is declared and set to the 
applicable interface depending on what USE flags were specified. 
However this variable is never used. It should be incorporated into econf: 
 
	econf \ 
		${guiflag} \ 
		..... 

Thanks for taking the time to look at this, FWIW I've just built libspectrum
with USE="-gnome" & fuse appeared to emerge correctly. It doesn't run correctly
however:

fuse: error: Unknown display size/image size 0/1

I'll try the suggested changes to the ebuild later today.

fixed in cvs with latest versions
