At least not until now. Even the development version has only one configure option that counts and this is --without-lcms build without lcms support So there are two possibilities. First there is no need for a jpg useflag as it will work out of the box. Second the jpg support or needed libraries if they are indeed needed are detected automagically which is bad and a bug should be filed.

Thank you Alan for your always helpful answers. While having nothing to
do I investigated a bit more on this issue and have something to add here.
First USE _jpeg_ should be enabled by default for desktop profiles.
I can view jpegs without problems in gqview and gqview doesn't require
anything jpeg related to view them. qgview only requires gtk+.
I took a look at the shared libraries (1) linked against gqview and with
the help of the reverse dependencies (2) of the packages owning that
shared libraries I was able to validate that gqview only needs gtk+
because all libraries used by gqview need gtk+ in some way. So the gtk+
dependency pulls in everything needed for gqview.
Now I took a look at the output of strace gqview (3). Here are the
relevant lines:
read(4, 5 \gtk20\ \The JPEG image format..., 1024) = 1024
stat64(/usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jpeg.so,
{st_mode=S_IFREG|0755, st_size=17756, ...}) = 0
open(/usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jpeg.so,
O_RDONLY) = 6
open(/usr/lib/libjpeg.so.62, O_RDONLY) = 6
Owners of the relevant libraries:
/usr/lib/gtk-2.0/2.10.0/loaders/libpixbufloader-jpeg.so is owned by
x11-libs/gtk+-2.12.11
/usr/lib/libjpeg.so.62 is owned by media-libs/jpeg-6b-r8
So gtk+ can open jpegs but why can't you on your system?
USE flags for gtk+:
x11-libs/gtk+-2.12.11 USE=X cups jpeg tiff -debug -doc -vim-syntax
-xinerama
The answer is gqview does not need a jpeg use flag nor does probably
feh, but gtk+ has to be built with jpeg support.
So there is no need for rebuilding world, adding the jpeg flag to gtk
should be enough. Or better if you use Gentoo on a desktop enable the
desktop profile. Plus instead of blaming Gentoo, learn how it works and
to use it properly. I know nothing about FreeBSD so I would not allow me
any prejudices against it. *sigh*
Just for your information I used the following commands for investigation
1) Packages needed by qgview by finding the owners of the shared
libraries needd by gqview:
ldd /usr/bin/gqview | sed -n 's/\s*\(.*\)\s=\s.*/\1/p' | xargs qfile
--nocolor
2) Reverse dependencies of said Packages:
ldd /usr/bin/gqview | sed -n 's/\s*\(.*\)\s=\s.*/\1/p' | xargs qfile
--nocolor | sed -n 's/\(.*\)\s.*/\1/p' | xargs emerge -pv
