Hi Wolfgang, I tried building 6.0.1 on Panther using 6.0.1 built on Jaguar. (The build was run under darwinports.) It failed with the following: ------------------------------------------------------------------------ ==fptools== make all -r; in /Users/gwright/src/darwinports/dports/lang/ghc/work/ghc-6.0.1/ libraries/base ------------------------------------------------------------------------ rm -f GHC/Base.o; if [ ! -d GHC/Base_split ]; then mkdir GHC/Base_split; else /usr/bin/find GHC/Base_split -name '*.o' -print | xargs rm -f __rm_food; fi; ../../ghc/compiler/ghc-inplace -H16m -O -I/opt/local/include -L/opt/local/lib -pgmP "gcc3 -E -traditional" -fglasgow-exts -cpp -Iinclude -#include HsBase.h -funbox-strict-fields -package-name base -O -Rghc-timing -split-objs -c GHC/Base.lhs -o GHC/Base.o -ohi GHC/Base.hi /tmp/ghc3798.split__111.s:unknown:missing indirect symbols for section (__DATA,__nl_symbol_ptr) <> make[2]: *** [GHC/Base.o] Error 1 make[1]: *** [all] Error 1 make: *** [build] Error 1 Warning: the following items did not execute (for ghc): com.apple.build

Ever see anything like this before? Best Wishes, Greg
