That doesn't seem to help... I'm not very up on awk, but it looks like
it is trying to write #!/bin/sh to a file called 'svnversion' :

jpollak at moya:~/src/myproj$ jam
REV is
...found 8 targets...
...updating 1 target...
Shell svnversion
/bin/sh: Syntax error: redirection unexpected

awk  '
NR == 1 { print "#!/bin/sh"  }
NR == 1 && /^[#:]/ { next }
/^##/ { next }
{ print }
' <  > svnversion 

...failed Shell svnversion...
...failed updating 1 target...
