gp2c trouble?

[Charles Greathouse <charles.greathouse@case.edu>]

I just built and installed the latest versions of gp and gp2c

GP/PARI CALCULATOR Version 2.6.0 (development git-982909e)

(there's no version number on gp2c that I can find, but it's the git
version from an hour ago).  gp runs and passed the bench, and gp2c
similarly runs and seems to have access to the 2.6.0 functions:

$ gp2c -l | grep 'ellheegner'
ellheegner ellheegner G

But when I try to load my gp2c file in gp it fails:

\r auto.gp.so
  ***   Warning: auto.gp.so is not a GP binary file.
  ***   error opening input file: `auto.gp.so'.
  ***   Break loop: type 'break' to go back to GP

I get a similar error if I use gp2c-run:

$ gp2c-run auto.gp.c

/auto.gp.so: cannot open shared object file: No such file or directory

  ***   at top-level: install("rev","GD10,
  ***                 ^--------------------
  *** install: couldn't open dynamic library '/auto.gp.so'.
  ***   Break loop: type 'break' to go back to GP

auto.gp.so exists and looks normal to me in a hex editor.  What could
be going wrong?
