DESCRIPTION:
Under Linux there is a ld(1) option

-soname=name
  When creating an ELF shared  object,  set  the  internal
  DT_SONAME field  to  the specified name.  When an executable is linked
  with a shared object which has a DT_SONAME field, then when the
  executable is  run  the  dynamic linker will attempt to load the shared
  object specified by the DT_SONAME field rather than  the  using  the
  file name given to the linker.

for setting a shared libraries DT_SONAME.

An application linked with a shared library with DT_SONAME
can detect at deployment time, if the library in LD_LIBRARY_PATH
has the right version. Without DT_SONAME being set it can occur
the application starts though, but shows strange error behaviour
during run-time.

COMMENTS:
Until now (6.0u8) libdrmaa.so delivered with N1GE is of version 0.95.
It is planned though to deliver in future releases a DRMAA 1.0 library
*plus* the old 0.95 compliant one.

WORKAROUND:
As workaround the application shall use drmaa_version() to ensure
LD_LIBRARY_PATH libdrmaa.so has the correct version.

There is a related problem with libdrmaa.so 0.95/1.0:

I just encountered libdrmaa.0.95.so (maintrunk) even had linking
symbols

   int drmaa_get_num_attr_names(drmaa_attr_names_t* values, int *size);
   int drmaa_get_num_attr_values(drmaa_attr_values_t* values, int *size);
   int drmaa_get_num_job_ids(drmaa_job_ids_t* values, int *size);

even though these functions actually are DRMAA 1.0 specific. I fixed
it (maintrunk). Now at least DRMAA 1.0 applications will fail with a
more reasonable error message, in case LD_LIBRARY_PATH libdrmaa is 0.95.

Added URL to thread with details on how to solve the -soname issue.

Fixed for in Maintrunk and S2-branch for Solaris and Linux
