looking at tcl/library/package.tcl, that appears to be the case 
indeed; tclPkgUnknown first looks for pkgIndex.tcl files and only 
uses tclMacPkgSearch to search for TEXT resources afterwards.

after sending my last message, it occurred to me that the question of 
using a no resource fork filesystem on the mac is moot anyway as the 
mac tclkit _executable_ most definitely needs a resource fork (for 
the 'cfrg' resource).

the question is how to setup mac files with a resource fork on a unix 
box, so that mkisofs does the right thing when building HFS+, I 
remember playing with this unsuccessfully a long time ago.

it's probably not possible to do macbinary from the script level, as 
the resource fork has to be read in a flat file manner for the 
macbinary format, which isn't possible through the tcl [resource] 
command. However, it should be easy to make a tcl extension from the 
public source macbinary code.

BTW, JC, I'm currently working on updating my tclkit patches to the 
vfs, tclkit & Tcl/Tk HEADs, to be able to finally answer your message 
from like a month ago, sorry for the delay... everything builds fine, 
but I've again run into some startup troubles with the init scripts, 
which I'm debugging now. hopefully I'll have a new build of tclkit 
soon, with only small patches to tclkit. (HEAD metakit & mktcl build 
& work flawlessly on the mac now btw, thanks)

Cheers,

Daniel
