The error "Unterminated <> operator at ./ipinfo.cgi line 90." is from this line:

print <
[download]

which appears to be a typo, most likely for a "here document" reference:

print <<END
[download]

But the reference to ${General::swroot} has just got to be defined in CONFIG_ROOT/general-functions.pl, so you need a copy of that file, as well as lang.pl and header.pl. There is no way that this can be a complete script by itself.
