I can check again tomorrow, but I don't think I used any io package 
functions.  I was trying to do an initial install of the io package just 
after installing a 4.1.0+ binary from the mxe-octave generated installer.

How can chk_spreadsheet_support be executed while still loading 
directories?  Can you provide a test case that demonstrates that 
problem?  It seems to me that if that is possible, then something else 
is wrong with the way PKG_ADD files are handled and we should look for a 
solution that problem instead of moving PKG_ADD files around in 
post_install scripts.
