     Am I the first one to put this on HP-UX, or are there any hints how to do it 
     
     ?

Sorry for not having answered faster to your question, but documentation about 
HPUX wasn't easy to find for me :)

It appears that HPUX uses a different shared library mechanism than most unix 
systems do. The common way is dlopen/dlclose while HPUX uses 
shl_load/shl_unload.

I do not have an HPUX system to test the following function wrappers. Tell me 
if those work well on your system:

Add the following functions in plugins.c;
Also replace #include <dlfcn.h> by #include <dl.h>;
Don't forget to update the function prototypes list (sproto.h) !

void *dlopen( const char *path, int mode )
{
    void *ret;
    ret = shl_load( path, BIND_IMMEDIATE | BIND_FIRST | BIND_VERBOSE, 0);
    return ret;
}

int dlclose( void *handle ) 
{
    return shl_unload( (shl_t) handle );
}

void *dlsym( void *handle, const char *sym )
{
    void *value=0;

    if ( shl_findsym( (shl_t*)&handle, sym, TYPE_PROCEDURE, &value ) != 0 )
        return 0;
    return value;
}

char *dlerror( void  )
{
    return strerror( errno );
}
