Created attachment 375640 [details, diff]
my attempt at patch to correct the error
When installing fltk on gentoo/prefix under osx 10.8.5 with apple gcc-4.2 , installation stage of the package fails . I tried to create a patch but the patch had no effect. I edited manually the files while compiling and the compilation passed.
Attached is my failed attempt at a patch.
The problem seems to be the rm command on a directory instead of a symbolic link
I bypassed the proble by adding -Rf in the Makefile
