emerge -av mkl fails when building "lapack" library just after building "blas" (libmkl_blas95.a) with lots and lots of errors (I'll attach the full output log + "emerge --info" later) if one uses the "fortran95" USE variable. (Intel Fortran Compiler v9.1.040 (dev-lang/ifc-9.1.040) was previously installed flawlessly.) I guess it's failing because both libraries are being compiled with "gfortran" instead of "ifort", despite the fact "ifort" IS installed and usable, but I don't know how to make "mkl" use "ifort". ("ifc" USE flag is set in make.conf since I installed the system.) If I clear the "fortran95" USE flag then it compiles flawless, but I need those libraries because of "ifc" USE flag, my system lacks "f77" or "g77".

I think I've got it !!! In order to make it compile with USE="fortran95", I just had to chdir into "/usr/i686-pc-linux-gnu/gcc-bin/4.1.1" (4.1.1 or active gcc version), and temporarily rename "gfortran" link to something else during emerging operation of "mkl", so it won't be detected (nor used) by the emerging process. (And of course, had to restablish it afterwards...) As for the impossibility of cleanly choosing "ifort" in the first place, I think it's related to "eselect-compiler" being masked. (See Bug #143697, amongst others.) Can't be sure at which point (if ANY at all, oh my poor memory...) I was asked by emerge to do an "eselect compiler <blah, blah...> ifort", or something like that. Thank you all...

It seems that gfortran-4.1.1 does not compile the fortran95 interface. Only ifort works. I fixed it in cvs, along with an update of mkl. It should automatically find ifc/ifort if you have it installed, by enabling the fortran95 use flag.
