Only available for Windows. IBM does not believe there is a need for other platforms to be supported. Only non-Windows option is manual config of Apache/IHS server separately. If you would like this option, IBM says to open a PMR.
"PMR requests for an IHS module for the Linux installation of Domino will increase weight added to the SPR and heighten awareness of customer needs. As always, this is welcomed."

Regardless if on Windows or LInux, you can install IKeyMan by installing the IHS server -- IHS is in one of the Websphere add-on "disks". A GSKit and IKeyMan folder/app is installed with the server.
