I have been working on a Perl @INC? issue for a couple of days for the program MisterHouse, which is a perl based home automation program.

The following piece of Perl code:

&my_use("Device::SerialPort");  # Unix Posix verion of Win32 SerialPort

causes a note on startup from perl:

Device::Serial could not find ioctl definitions!

I have copied into a couple other places thinking it might be path related, but that has not resolved the matter.
