Compilation errors (file-entities.ent cannot be fopen'ed)

Hello, When trying to compile the PHP documentation, I keep getting the same error: ERROR: Failed to open /home/cheezy/phpdoc-nl/entities/file-entities.ent for writing I have searched the list archives, but could only find older articles dealing with this problem, and they couldn't help me. It seems that all calls to fopen in scripts/file-entities.php fail, but I have no idea why. If I try to fopen file-entities.ent from another php file, it works. I am using the PHP that came with Red Hat 9 (one upgrade), 4.2.2[-17.2]. The directory is writeable, if I touch the file and test if it is_writable from file-entities.php, it all works, only the fopen fails. I have checked out the latest version of the documentation as phpdoc-nl, autoconf works, and then configure fails. Any pointers to more information are appreciated. Greetings, Jan Fabry
