Webalizer make på slackware

Jeg giver den denne cmd efter at have compilled / maked zlib, gd, libpng osv...

root@Slackie:/usr/local/webalizer-2.01-10# ./configure --with-gd=/usr/local/src/gd --with-zlib=/usr/local/src/zlib --with-png=/usr/local/scr/libpng

Altså ./configure lykkede 100% som jeg ser det... Men så opstår der et problem som jeg ikk lige kan se årsagen til når jeg giver den;

root@Slackie:/usr/local/webalizer-2.01-10# make

Nogen som kan sige hva denne fejl lige betyder? og hvordan den løses... ?

På forhånd tak...
