Hi Michael, I now think it is in fact a sage bug. Harald schilly had a slightly different version of that a month ago or so (with ecl or ecls in Gentoo speak).
The problem is that you are in the sage environment and LD_LIBRARY_PATH set by sage is hiding the system libgd. If you look at the system libgd: objdump -T -C /usr/lib64/libgd.so.2 | grep gdImageCreateFromJpegPtr You should that see the symbol is defined: 00000000000168a0 g DF .text 000000000000003b Base gdImageCreateFromJpegPtr But if look at objdump -T -C ${SAGE_ROOT}/local/lib/libgd..so.2 You won't get anything because by default gd is compiled without jpeg support in sage.
