Just thought I'd update you.
I tested PIL with the Sun compiler (Sun Studio 12 update 1), which I
downloaded for my own machine a few days ago. I used:
$ ./sage -i pil-1.1.6
PIL respects 'CC' (i.e. it uses the Sun compiler, not gcc). It also uses
the correct flags to generate the position independent code
(-xcode=pic32, though -KPIC would work too). An example line is below:
/opt/sunstudio12.1/bin/cc -DNDEBUG -O -xcode=pic32 -DHAVE_LIBJPEG
-DHAVE_LIBZ -DWORDS_BIGENDIAN
-I/export/home/drkirkby/sage/suncc/sage-4.1.1/local/include/freetype2
-IlibImaging -I/export/home/drkirkby/sage/suncc/sage-4.1.1/local/include
-I/usr/local/include -I/usr/include
-I/export/home/drkirkby/sage/suncc/sage-4.1.1/local/include/python2.6 -c
_imaging.c -o build/temp.solaris-2.10-sun4u-2.6/_imaging.o
There are no GNU-isms there!!

Successfully installed pil-1.1.6
So PIL build from the Sage prompt on Solaris with *both* the GNU and Sun
compilers on Solaris, with no serious problems!
There are a few compiler warnings. If the person wishing to add this is
the original author, perhaps he would like to address them, but
otherwise that builds ok. I have NOT checked the functionality of it.
I've list a few compiler warnings below for completeness. If anyone
wants complete log of the build of PIL I can send it.
So whilst I don't know much about the package, it builds fine, so I
certainly have no objections to it's inclusion.

Warnings are:
1)
"libImaging/ZipEncode.c", line 310: warning: statement not reached
2)
"libImaging/GetBBox.c", line 57: warning: initializer does not fit or is
out of range: 0xffffffff
"libImaging/GetBBox.c", line 98: warning: initializer does not fit or is
out of range: 0xffffffff
3) The following warning appears multiple times, and many lines.
