I'm running Gentoo 2.6.0. I needed an easy way to convert .eps and .pdf files to web safe images. I ran emerge imagemagick and everything wen smooth as butter.

When I use imagemagick to convert from pdf or eps to let's say .jpg I ran this command:
convert test.eps test.jpg

I received the following output:
convert: no decode delegate for this image format `test.eps'.

After a quick google search it turns out I need ghostscript installed to be able to read these two formats. So I ran:
emerge ghostscript

Here lies my problem. Emerge fails providing only this:
!!! ERROR: x11-misc/shared-mime-info-0.19 failed.
Call stack:
ebuild.sh, line 1614: Called dyn_compile
ebuild.sh, line 971: Called qa_call 'src_compile'
environment, line 2968: Called src_compile
shared-mime-info-0.19.ebuild, line 26: Called die

!!! (no error message)
!!! If you need support, post the topmost build error, and the call stack if relevant.
!!! A complete build log is located at '/var/tmp/portage/x11-misc/shared-mime-info-0.19/temp/build.log'.

When I view the log file listed above, I see the same error that was output on the screen when emerge failed. I tried running:

emerge shared-mime-info-0.19

and I receive:

!!! 'shared-mime-info-0.19' is not a valid package atom.
!!! Please check ebuild(5) for full details.
!!! (Did you specify a version but forget to prefix with '='?)

So now I'm at a loss. Any thoughts on where I should look next?

try emerge --pretend ghostscript and post the output

Here is the output for emerge --pretend ghostscript:

gentoo jjsp # emerge --pretend ghostscript

These are the packages that would be merged, in order:

Thanks.
