ok, I've made some progress, albeit a slight digression from what we're
trying to achieve. Note that this is with the May 18th code snapshot.

I managed to build the mono beta 1 by doing the following:

./configure --prefix=/usr/local --with-gc=none
gmake
edit data/config to change libc mappings to libc.so.4
gmake install

voila!

spark% mono --version
Mono JIT compiler version 0.91.99.20040518, (C) 2002-2004 Novell, Inc
and Contributors. www.go-mono.com
        TLS:           normal
        GC:            none
        SIGSEGV      : normal
        Globalization: none

I then proceeded to download and compile xsp-0.13. There were no
problems with the compilation and installation of xsp. I tried running
it and got the following stack trace when making my first request:

(note: started in /usr/local/share/doc/xsp/test )

Hit Return to stop the server.

Therefore I take it that xsp requires a garbage collector to run. I
downloaded and installed the boehms GC that you linked to. That went
well, but gcc is not finding the library:

spark% gcc -lgc
/usr/libexec/elf/ld: cannot find -lgc

I built boehms GC using --prefix=/usr/local

Here's the contents of my /usr/local/lib/libgc*

spark% ls -la libgc*
-rw-r--r--  1 root  wheel  473908 May 18 19:19 libgc.a
-rwxr-xr-x  1 root  wheel     685 May 18 19:19 libgc.la
