Hi Christopher,

Since sage-on-prefix is semi-official I though I would indicate an  
issue I encountered in installing Sage from sage-on-gentoo in a prefix  
on Debian Linux.

When building sympow (sympow-1.018.1_p8-r1) the Debian system gcc  
compiler was being used instead of the Prefix gcc. This was because  
sympow provides in Configure a whichexe() function with hard-coded  
search paths. The easiest thing for me was to add:

         # fix EPREFIX in whichexe() function
         sed -i -e "s:-f \/bin:-f ${EPREFIX}\/bin:" \
                 -e "s:echo \/bin:echo ${EPREFIX}\/bin:" \
                 -e "s:\/usr:${EPREFIX}\/usr:g" \
                 Configure || die "failed to fix EPREFIX in whichexe()"

to src_prepare(). I didn't think about it until just recently, but  
perhaps the hard-coded paths could be removed so the prefix/gentoo  
system 'which' is used.

Steve

Hi Steve,

I almost fell like forwarding that one to Dave on sage-devel for
a laugh. It looks like a fairly decent fix to me.

I am not back on duty but at least I read my email.

Yes, I simply replaced "whichexe " with "which ", which should do it.
