You do need these useless rewrite's and if's:
  rewrite ~/(.*)$ /$1 last;
  if (!-e $request_filename) {
  if ($request_filename ~ javascript) {

Here is configuration:

 server {
  listen   81;
  server_name  dev.mysite.com;
 
  root /home/my_linux_user/www/dev/mysite/trunk/html/public;
  index index.php;
 
  access_log  /var/log/nginx/dev_mysite.access.log;
  error_log /var/log/nginx/dev_mysite.error.log;
 
  location / {
     error_page  404 = /index.php?q=$request_uri;
  }
 
  location ~* (jpg|jpeg|gif|png|js|css) {
      expires    30d;
      access_log off;
  }
 
  location ~ \.php$ {
    fastcgi_pass  127.0.0.1:10005;
    fastcgi_param SCRIPT_FILENAME 
 /home/my_linux_user/www/dev/mysite/trunk/html/public$fastcgi_script_name;
    include /etc/nginx/fastcgi_params;
  }
 
  location /javascript/ {
     rewrite ^/javascript/(.*)$ /combine.php?type=javascript&files=$1 last;
  }
 
  location /tmp/ {
  }
 
  location /filestore/ {
  }
 
  location /cgi-bin/ {
    fastcgi_pass unix:/tmp/cgi.sock;
    include /etc/nginx/perl_fcgiwrap_params;
  }

 }
