Which platform - Mac OS X, Linux or Win32 is best for development with GHC today? How are things with Ubuntu? It was quite a while already that I used Haskell on Linux. Today I have to code on Win32 and Mac OS X. Installing extra libraries caused most of the pains for me on Win32 - for example GTK and Gnuplot is not easy to install on Win32. Installing GTK on Max OSX is also a hard work, but no problems with Gnuplot at all. Haskell mode for Emacs works fine on Mac OS X, but only to some extent on Win32. I have not managed to start GHCi in Emacs buffer on Win32. Haskell Win32 Platform also has a weird bug of missing documentation on some widely used modules from Haskell Hierarchical Library. I understand that Linux should be a much better environment for integrating with external libraries (just because most of them were originally developed for Linux). I don't want to start religious wars, yet I wonder on what platform Haskell run-time works best and development has minimum obstacles? Thanks!
