wget/curl is not a replacement for the fopen() function call.
Presumably your sys-admin has the idea that locking down a specific
function call, will help reduce their likelyhood of being 'owned'.
Additionally, fopen() is used in lots of programs that reads/writes
local files, so this restriction would break a huge amount of code.
H::T uses the perl function "open()" to read the file, which
(presumably) is calling the underlying system call "fopen()". One
possible solution might be to use the LD_PRELOAD environmental variable,
to intercept fopen(), then redirect it to wget... (good luck with that... :)
Other than that, I'd suggest you ask your sys-admin to fix their
security policy....
