error 75 on Linux server?

[Richard Gaskin]

I have a CGI on my Debian server at Dreamhost which reads file using 
"put url ("binfile...", and it's been working well until a recent change 
to their server, and now it doesn't read the file, with "can't read 
file" in the result and sysError return 75.

Oddly, it seems that replacing the "put url" call with open/read/close 
allows it to work.

I don't necessarily mind replacing those calls, but what is error 75 and 
what could cause "put url ("binfile:<path>") to fail while 
open/read/close succeeds?
