I had an equivalent issue with my ubuntu 12.10 and png2swf utility.
Actually, libjpeg.so.62
didn't exist. But it's likely a link to a hard file.
a 'locate libjpeg'
listed among others
/usr/lib/i386-linux-gnu/libjpeg.so.8
/usr/lib/i386-linux-gnu/libjpeg.so.8.0.2
My quick and dirty fix was to create a symbolic link to libjpeg.so.8.0.2, in superuser mode
ln -s /usr/lib/i386-linux-gnu/libjpeg.so.8.0.2 /usr/lib/i386-linux-gnu/libjpeg.so.62
Bear in mind that some libs differ not that significantly across versions. Well, I was lucky but sometimes simple fixes might solve small issues, not always true though.
You may also wish to read about the ldd command, and verify that a missing shared-library is not present.
