I tried to install both, drscheme installed fine, but mzscheme wouldn't 
compile.  Then I checked, and drscheme installs a mzscheme binary which 
tells me:

The other mzscheme package was version 250 or so, much older.

First thing I did was change prefix to /home/claude , which probably 
wasn't the wisest move, given the outcome..

Then I had to hack SConstruct because Gentoo's drscheme keeps its stuff in:

/usr/lib/drscheme/include/scheme.h
/usr/lib/drscheme/lib/libmzgc.a

etc

Then the old PNG issue cropped up:

Checking for main() in C library png... no
ERROR: 'png' must be installed!

Relevant files are found using:
pkg-config - Return metainformation about installed libraries

On my system:
$ pkg-config libpng --cflags
-I/usr/include/libpng12
$ pkg-config libpng --libs
-lpng12

And libpng docs state you should #include <png.h> and not any variant 
like #include <libpng/png.h> ...

Then I had to change all
#include <plt/scheme.h>  -> #include <scheme.h>
#include <plt/escheme.h> -> #include <escheme.h>

Then I got:

g++ -o fluxus-0.12 src/GLEditor.o src/Interpreter.o src/Repl.o 
src/Utils.o src/Recorder.o src/FluxusMain.o src/main.o -L/usr/lib 
-L/usr/lib/drscheme/lib -L/home/claude/libfluxus -L/usr/X11R6/lib -lm

/usr/lib/drscheme/lib/libmzscheme.a(env.o): In function 
`read_resolve_prefix':
: undefined reference to `GC_malloc'

plus several more pages of errrors, fixed by switching the order of 
mzsheme and mzgc in the tests (and thereby the libs linked).

scons: *** Source `/usr/lib/plt/mzdyn.o' not found, needed by target 
`modules/fluxus-audio/fluxus-audio.so'.  Stop.

-> /usr/lib/drscheme/lib/mzdyn.o

Finally 'scons' completed successfully, but I had to abort 'scons install' :

[ at this point scons used a large amount of cpu time and more than my 
physical RAM of 1GB, so I killed it because my system was becoming 
sluggish due to excess swapping ]
Terminated

Any ideas on this issue?

I tried running it anyway, but got:

$ ~/bin/fluxus-0.12
default-load-handler: cannot open input file: 
"/usr/local/lib/plt/collects/fluxus-0.12/fluxus-boot.scm" (No such file 
or directory; errno=2)
$

Naturally, having changed prefix, the file is here:

/home/claude/lib/plt/collects/fluxus-0.12/fluxus-boot.scm

PS:

The INSTALL file still says:

requires:
guile      http://www.gnu.org/software/guile/guile.html
