I'm developing some cgi programs using perl5.002, and sybperl 2.07 and am having very unpredictable behavior from the httpd server. noe perl errors or problems appear when these programs are run from the command line, however, when I run them from the Web browser, I get numerous 'malformed header from script' errors.

Ah ok, makes sense.

If anyone does something in perl that uses both perl's output and
something that exec(3)s something, the perl output will not necessarily be
flushed before the other output happens.
eg.
#!/usr/local/bin/crey
print "Content-type: text/plain\n\n";
system("/bin/ls");
will fail on many systems because the output from ls happens
before perl flushes its buffers. A similar thing happens in C
on many systems. On some systems, you will never run into
this problem.

Why are we recommending $| = 1 all the time? I've never had to do this in
my CGIs.

Have you checked the error log? This is almost certainly a bug in your
CGI script. Try adding "$| = 1;" near the start of your program and be
sure you correctly output the header.
