(CCing gentoo-sci@l.g.o, as i guess i'll thus reach the majority of icc
dependant Gentoo users)

I'll appreciate any help I can get on that :-)

Some of my thoughts on current problems (w/o having searched bugzilla yet!)

dev-lang/icc and dev-lang/ifc
 * No support for icc/ifort in (g)cc-config.

 * Different naming schemes for distributed packages. A friend of mine
   has a l_intel_cc_pu_${PV}.tar.gz for his academic work. I got a
   l_intel_cc_p_${PV}.tar.gz from Intel's premier support... go
   figure... :-/ Is it valid to specify
      SRC_URI="|| ( file1 file2 )"
   in an ebuild ? Or can we use wildcards in SRC_URI?
 * icc depends on gcc's libstdc++, so changing your gcc version affects
   icc and can even break it.

sci-libs/mkl
 * integration in current virtual/{blas,lapack} scheme is missing (but
   in the works for app-admin/eclectic)
 * some lapack functions have uncommon naming scheme ('z' prefix where
   'd' would be expected.)
 * distributed via binary installer that has a rpm file as payload which
   can't be extracted. Up to now, i always have to run the installer
   once to obtain the rpm file.

all of the above
 * New versions need fetch restrictions turned on. This means for all
   users of the old (and free as in beer) versions some nastiness for
   the next update. Also, the old versions would be removed:
   Slotting? if yes, based on what?

icc/ifc use flags:
 * These are scary. Using a different compiler should not be achieved
   by setting a useflag, neither local nor global one.

I'd like to have some feedback on these problems :-)
