Version 1.8.2 of PIL (May 2002) compiles on the following architectures :
sparc-sun-solaris (32 / 64 bit) intel-gnu-linux (32 bit)
The library may compile/run on other architectures (we have reports of successful compilation on HP-UX, mips-sgi-irix and alpha-dec-osf machines), but PIL development team has access only to those aforementioned. Furthermore ISDC officially supports only "reference platform", which is defined as sparc-sun-solaris running Solaris 8 with Forte 6 compiler set. Refer to :
