As initially reported in pkgsrc-users@

Seems luajit is reactivated, and one of its assembler files generated (lj_vm_asm.S) destined to be put in a shared library is non-PIC.

Looks like gnu-ld is tolerant of R_*_PC32 relocations here, but sun-ld wants R_*_PLT32 else it balks with:

This should be fixed correctly upstream, but a temporary workaround in pkgsrc may be the following patch:

richard@omnis:/home/richard/src/pkgsrc/print/luatex$ cat patches/ 
Ensure that the luajit generated asm file is PIC for libtool use, particularly
important when linking under SunOS... appending @PLT seems to workaround the
issue with generated PC relative calls.

BTW I needed to add 'gsed' to USE_TOOLS in order to use the simplified
inplace option to sed which nbsed doesn't support.
