For the past several years, I've had to keep acroread installed on one of my desktop machines because I occasionally need to use the "print current view" feature to print a portion of a page of a PDF document (usually a section of a sechematic or a table out of a data sheet). Acroread is only available as a 32-bit binary and it required that _89_ packages be built with a 32-bit ABI use flag. [There are various other reasons to dislike acroread, but that's the one the really bugged me...]
When I noticed that the latest versions of Qoppa's PDFStudio has added the "print current view" feature, I happily coughed up the $36 to upgrade. Emerge is now busy rebuilding those 89 packages without the 32-bit ABI use flags. -- Grant
