I would like to use the exiftool library for exif/iptc/xmp image  
metadata  
manipulation, but it’s written in Perl. Since it seems somehow wrong and  
definitely inefficient, I was wondering if there was any sort of  
perl2ruby  
convertor, or if there was an inline::perl module that could at least  
take  
the Perl and compile it to bytecode.

None of these are suitable?

$ gem search -r exif

\*\*\* REMOTE GEMS \*\*\*

exifr (0.10.8)  
extexif (1.0.1)  
mini\_exiftool (1.0.1)  
multi\_exiftool (0.0.1)

Both are exif-only. EXIF is the metadata the camera writes. It is  
writable/modify-able, but mostly to add gps info, or correct dates.  
IPTC and XMP have fields to add much richer metadata: caption,  
description, keywords, etc.

Both are interfaces to the Perl based exiftool mentioned above.
