Bug 70482

hmm, weird, there is already a -lm in libgsl_la_LIBADD for me. that should already fix this problem, right?

Yes, indeed, I cannot reproduce this error anymore on my x86 box, so I suspect the bug's gone (for whatever reason; I didn't find anything in the cvs logs).

Hmmm, I just started a fresh compile on our SPARC systems now, and unfortunately it fails (I've removed the "--silent" option for libtool, and rebuilt libgsl.a; see below).

The only difference between the x86 and SPARC systems I can think of right now is that I use the GNU binutils ony my x86 box whereas I rely on Sun's linker/assembler on the SPARC systems...

It seems that I need the following patch in this case for SPARC (I just successfully compiled arts with it, will try the same on x86 this evening):
