exec/system on FreeBSD help?

I've been trying to figure out why a command like exec()/system() works fine under windows and it doens't seem to run on FreeBSD. I've got a script that generates a latex file, runs pdflatex, and then moves the pdf file into a "reports" with a link on the generating page. Works fine on Win2k but when I try to run it on the BSD machine, it doesn't look like the commands are getting issued, or that I can't run the commands because of file permissions. I've chmod'd the dir for the website and that didn't seem to help. I tried some small script like exec("ls -la") and that worked. I then tried system( "/usr/local/bin/pdflatex temp/report_file" ); to try and diagnose the problem, and got "Fatal Error occured, I can't write on file 'report_file.log', suggesting that there might still be some permissions problems. Maybe this is a apache thing? Any ideas? -- Jeff D. Hamann Hamann, Donald & Associates, Inc.
