fastcgi incomplete headers issues

[blunt]

well i'm having the same problem, and can't figure out how to correct it...

I tried executing through sudo:
sudo -u vu2000 /var/www/fcgi/master/php5-fcgi-starter /var/www/ispcp/gui/index.php
sudo: unable to execute /var/www/fcgi/master/php5-fcgi-starter: Permission denied

here are the permissions of the dir:
ls -la /var/www/fcgi/master/
total 36
drwxr-xr-x 4 vu2000 vu2000 4096 Jan 3 11:12 .
drwxr-xr-x 3 vu2000 vu2000 4096 Jan 3 11:12 ..
-rw-r--r-- 1 vu2000 vu2000 220 Jan 3 11:12 .bash_logout
-rw-r--r-- 1 vu2000 vu2000 414 Jan 3 11:12 .bash_profile
-rw-r--r-- 1 vu2000 vu2000 2227 Jan 3 11:12 .bashrc
drwxr-xr-x 2 root root 4096 Jan 3 11:12 php4
-rwxr-xr-x 1 vu2000 vu2000 195 Jan 3 11:12 php4-fcgi-starter
drwxr-xr-x 2 root root 4096 Jan 3 11:12 php5
-rwxr-xr-x 1 vu2000 vu2000 195 Jan 3 21:25 php5-fcgi-starter

any help is much appreciated
thank you
