I've been trying to get into experimenting with YARV lately,  but
haven't had much success building the SVN or latest tarballs, although I
have managed to build 0.4.1 and am running the benchmarks right now.
Miniruby gets built just fine, however, but once it comes time to build
the extensions I run into weird problems.  With the current SVN I get
the following:

./miniruby ../yarv-svn/mkconfig.rb -timestamp=.rbconfig.time \
                -install_name=ruby-yarv-svn \
                -so_name=ruby-yarv-svn rbconfig.rb
rbconfig.rb updated
./miniruby ../yarv-svn/ext/extmk.rb --dest-dir="" --make="make"
--mflags="" --make-flags="" --extout=".ext" --extension  --extstatic  --
compiling Win32API
compiling bigdecimal
make[1]: Entering directory `/home/dido/progs/yarv-svn-build/ext/bigdecimal'
Makefile:143: *** missing separator.  Stop.
make[1]: Leaving directory `/home/dido/progs/yarv-svn-build/ext/bigdecimal'
make: *** [all] Error 1

A look ext/bigdecimal/Makefile line 143 shows the following garbage:

.cc.|#_!!_#|o:
        $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $<

.cxx.|#_!!_#|o:
        $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $<

.cpp.|#_!!_#|o:
        $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $<

.C.|#_!!_#|o:
        $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c $<

.c.|#_!!_#|o:
        $(CC) $(CFLAGS) $(CPPFLAGS) -c $<

The rest of the Makefile is shot full of these very strange |#_!!_#|
characters.  What is going on here?  I had to use my local autoconf
(2.60) to do the build; perhaps that has something to do with it...

I'm trying to build it on Gentoo Linux, and have got the following:

Base Ruby:

ruby 1.8.5 (2006-08-25) [i686-linux]

I also have Ruby 1.9:

ruby 1.9.0 (2006-09-29) [i686-linux]

but using this as baseruby gives me this error:
