ok
if /usr/bin/gcc-4.0 exists but /usr/bin/gcc does not point to it,  
it's not right ?

ok

checking Mac OS X version... 10.4.11
checking Xcode version... 2.4.1

ok

i would like to install as less as possible
which part of xcode do you think is necessary, please ? :-)

developer tools software ?
gcc 4.0 ?
software development kits ?


btw,

why does it work fine to build MacPorts itself, with gcc 3.3, and not  
to build software ?

why does it say :
checking for gcc... /usr/bin/gcc-4.0
checking for C compiler default output... configure: error: C  
compiler cannot create executables
rather than sth like
checking for gcc... /usr/bin/gcc-4.0 not found
?
and why not searh for gcc-4.0 in $PATH ?
