i think i should give some more information. "./configure" does without any errors. The error occurs while doing "make". The last lines of makes output: && rm -f tmp-gdk-pixbuf-enum-types.h \ && echo timestamp > s-enum-types-h /usr/bin/env: perl -w: No such file or directory make[2]: *** [s-enum-types-h] Error 127 make[2]: Leaving directory `/home/meeb/work/gtk+-2.10.6/gdk-pixbuf' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/meeb/work/gtk+-2.10.6'
