Thanks for the contribution!  I have a few concerns about your proposed
changes that I address below.

A kde menu entry would be nice, but I'm not the person to do it due to
my unfamiliarity with all things kde :)  Perhaps we could appeal to the
kde developers (danarmak, et al) for assistance or maybe a clueful kde
user.

My problem with this is a constantly changing R installation associated
with a fixed ebuild revision.  This would make troubleshooting user
problems (i.e. submitted bug reports for R, for which the most likely
resolution would be INVALID: try again tomorrow :) a nightmare as user's
who installed on Monday, Tuesday, Thursday, and Sunday have no problems,
while something goes wrong with the build or running the app for users
who merge on Wednesday, Friday and Saturday. Also not having a md5sum
check on a download from an outside source will not appeal to the
paranoid.

However, having said that, the option of having a R install with all the
latest and greatest bugfixes applied is appealing.  I might be amenable
to having a separate R-daily_release-1.4.1.ebuild to supplement the
existing conventional one as long as it is understood that merging is
potentially a crapshoot and may come up snake eyes.  This situation is
similar to the CVS snapshot feature that has been frequently discussed.

If we have a daily_release ebuild, I would also like to make the
following changes to your implementation.

1. Remove the downloading line from src_unpack and put it it pkg_setup.

2. Download the patch to DISTDIR so the daily patch applied is available
for future reference and/or scrutiny. 

2. Utilize the FETCHCOMMAND variable so the user specified downloader
will be used.

I will solicit the opinions and counsel of other developers on this
issue and we'll see if we can implement this feature in one form or
another.

Once again, thanks for the contribution and keep it up.
