After discussion about GUIs zeronoise on mac here is what I've managed. I posted in new topic in case it was missed. I got the windows installer for zn 0.9 from guis sites, installed and overwrote the exe (in home/user/.wine/drive_c/zeronoise in this case) with updates 1.04.
Then tried using it, worked but couldn't direct to my actual dcraw (in usr/bin) complied for my OS. Used prebuilt windows dcraw.exe from www.insflug.org/raw/ version 8.93 and dropped it into virtual windows root (home/user/.wine/drive_c and in a folder called dcraw on this virtual root).
Works fine everything good. Only issue is I have to use a windows compiled one so each time I update my dcraw on my system it wont affect this since the actual linux binary wont work as zn will look for the exe in windows root. It's just a matter of getting a precompiled windows dcraw.exe and sticking in right place so not a problem. One for the future gui (guillermo that is, not a future front end for dcraw ) is perhaps giving the option to set path to dcraw (although it will need to look for binaries not win executable), however it's not issue IMO since it runs in wine so making cross platform installer isn't really a must.
Oh on a side note I needed to register msstdfmt.dll with wine, simply open console (I'm in kde so use konsole) and type following from same location as dll (or preceed with path etc)
wine regsvr32 msstdfmt
Since this works for me it should work for all linux users as I'm a slackware (and recently zenwalk) man so pretty good representation of other linux boxes since it's not that modified (ie. debian is a world of it's own so what applies to deb doesn't always apply to other distros but what applies to slack tends to apply to linux in general). Since it works in wine bsd users are fine too along with solaris users etc since wine tends to work on most common unix variants. Which brings me to mac, wine / darwine is available so should work for you too, unfortunately I don't have mac experience to share but my experiences here prove it's more than possible. All good news I guess Extra info you might need, I'm using wine version 1.1.14 and set to windows xp with no dll overrides and all default global settings (as far as zn goes anyway). Might be worth running winecfg to check it's in xp mode (usually best option).
