Thanks Jamie,

I used fink (fink commander) and installed gsl (which i think i already did)

the install looked ok - the last couple of lines of the output read:

Unpacking gsl (from .../gsl_1.3-1_darwin-powerpc.deb) ... Selecting previously deselected package gsl-shlibs. Unpacking gsl-shlibs (from .../gsl-shlibs_1.3-1_darwin-powerpc.deb) ... Setting up gsl-shlibs (1.3-1) ... Setting up gsl (1.3-1) ...

• gsl-ref: (gsl-ref). GNU Scientific Library - Reference

install-info(/sw/share/info/gsl-ref.info): creating new section `Scientific software'

but when i tried to ./configure again on pdp i got the same error

Thanks for your help - i've just moved over from windows and this unix stuff is still very new to me!
