[ELDK] eldk installation mktemp cannot make tempdir eldk_install.xxxxx

[汪政]

Dear:
      during the installation of ELDK-5.2.1,  I get into troubles as
following , ofcourse, i guaranty that all files are coming from denx, and
their sha256sums are correct.
executing "./install.sh -s gmae -r "minimal-dev sato-sdk" powerpc-e500v2"
prompting messages: "mktemp invalid option", then i  check "install.sh",
find "mktemp" command used not properly just like "mktemp -d
--tmpdir=${inst_path} eldk_install.XXXXX--" , which according to "man
mktemp" shoul be "mktemp -d -p=$...."

but after i changed according to that, prompt the message " cannot  make
tempdir eldk_install.xxxxx"


how can i solve the problems?
regards
